[JDEV] Jabber Test Suite compiles on more platforms now..
Jabber Test Suite The Jabber Test Suite, a testing harness for Jabber servers that tests message throughput and connection rates, has been updated to be portable on most UNIX systems. As of version 1.0.2 the source code has been compiled on Linux, FreeBSD, Solaris, and SunOS.

[JDEV] Minor notes about JabberTest
This is just a quick note to let everyone know that I uploaded a source tgz of JabberTest to www.sf.net/projects/jabbertest. I have received a very large number of requests recently for a source package since most people seem to prefer to avoid CVS. In addition, I made some very minor modifications to the documentation, including adding an INSTALL document. On a related note, I will be performing a number of updates to the test suite in the coming months. If you have any wishes you would like to see addressed, then don't hesitate in letting me know. So what is JabberTest? JabberTest is a GPL'd testing harness for Jabber to test performance and delivery. The software includes several tools to perform various tests, including timing of account creation, message delivery, and concurrent session limits. Any combination of tests can be performed at the same time to test different characteristics of the Jabber.org or Jabber.com servers and the hardware infrastructure. If anyone has any questions then let me know. I can be reached at [EMAIL PROTECTED] FYI, I am not subscribed to jdev or jadmin due to high list traffic.

[JDEV] setting presence generates odd error?
We are working with Jabber 1.4 under AIX thanks to Matt Diez. I am
setting my presense using:
presence statusonline/status showonline/show/presence
In error.log I get:
20010830T20:12:42: [warn] (-internal): jsm: Invalid Recipient, returning
data presence from='[EMAIL PROTECTED]/Receive'
statusonline/status showonline/showx xmlns='jabber:x:delay'

statusonline/status showonline/showx xmlns='jabber:x:delay'
from='[EMAIL PROTECTED]/Sender'
stamp='20010830T20:12:44'//presence
This doesn't happen under Jabber 1.4 on a Linux box, at least not that I
can see. At first I was using Available instead of online, but Matt
suggested I try online. Both generate the above error.
Am I doing something wrong, or is jabberd burping?
Before I started working on this I was also using the show/ tag:
int xml_set_presence(char *buf, int maxlen, char *status, char *show)
{
snprintf(buf, maxlen,
presence
status%s/status
show%s/show
/presence,
status, show);
return 1;
}
Pretty simple, eh? I'm curious what I am doing wrong, if anything.

[JDEV] User logins slow down?
We are playing with jabberd under AIX. I was running pasvlogin from the jabbertest tools and noticed that as the number of logged in users increases the login time increases. Under both Jabber 1.4 under Linux and AIX it grows from .1 seconds to .7 seconds as n = 1 - 1000. Is that expected? Should login time increase as the number of online users increases?

Re: [JDEV] Sparse considerations about server status
I had some time yesterday and today to play with jabbertest and jabberd 1.4.1 and here are my results. First, my changes to jabbertest: both the msgloadsnd and msgloadrec clients are now checking for closed sockets. In addition, msgloadsnd is watching for bounced messages. Okay, so I first tested my socket handling code by running jabbertest with 5 user pairs sending 3 messages/sec for 60 seconds. Once the test begins I manually kill jabberd. Both the msgloadsnd and msgloadrec clients report that their sockets were closed and then abort. So that works. I then restart jabberd and run jabbertest with 200 user pairs sending 2 messages/sec for 60 seconds, which gives me the following stats: UserPs Rate Duration MinDelTime MaxDelTime AvgDelTime MsgCnt ExpMsg MsgLossRate 2002 60 0.01704440.68959 151.83634 14322 24000 0.40325 That's a 40% loss rate for a 400 messages/sec test. I look in error.log and see a lot of: 20010816T18:17:36: [notice] (elavil): bouncing a packet to test_77@elavil/Receiver from test_76@elavil/Sender: Socket Error to Client 20010816T18:17:36: [notice] (elavil): bouncing a packet to test_77@elavil/Receiver from test_76@elavil/Sender: Socket Error to Client 20010816T18:17:36: [notice] (elavil): bouncing a packet to test_77@elavil/Receiver from test_76@elavil/Sender: Socket Error to Client 20010816T18:17:36: [notice] (elavil): bouncing a packet to test_77@elavil/Receiver from test_76@elavil/Sender: Socket Error to Client 20010816T18:17:36: [notice] (elavil): bouncing a packet to test_77@elavil/Receiver from test_76@elavil/Sender: Socket Error to Client ... This happens to several test_ users, not just test_76. Ok.. so does this must mean the sockets are getting closed somewhere? I checked both ends and none of my clients have reported a socket closed condition. Must be something else. However, I do find a [very] few of the following reported from msgloadsnd, which is catching bounce messages: [dpuryear@zoloft dpuryear]$ head s.test_76 msg: 7 997985807 901646 I think it is about time to say bye-bye to ICQ, AIM, and MSN! msg: Offline Storage msg: Socket Error to Client msg: Socket Error to Client msg: 8 997985808 411677 I think it is about time to say bye-bye to ICQ, AIM, and MSN! msg: Offline Storage msg: Socket Error to Client msg: Socket Error to Client msg: 9 997985808 921620 Are you serious? You want to do what with Jabber? msg: Offline Storage I assume the int int int string messages are bounces? Regarding Offline Storage I assume that just means jabberd is putting the message into offline storage because it lost contact with the receiving client, as I confirmed by looking at the test_77.xml file: [root@elavil jabber-1.4.1]# ll spool/elavil/test_77.xml -rw---1 jabber jabber 15110 Aug 16 13:19 spool/elavil/test_77.xml (Odds are receivers and evens are senders, so test_76 sends to test_77.) But notice that I got an Offline Storage message _before_ a Socket Error to Client message. What happened there? And why isn't my receiving client getting a socket closed condition? None of the clients ever report that their socket has been closed. Also, I don't always get warnings or notices from jabberd. For example, examine the following: 20010816T18:24:06: [notice] (elavil): bouncing a packet to test_391@elavil/Receiver from test_390@elavil/Sender: Socket Error to Client 20010816T18:24:06: [notice] (elavil): bouncing a packet to test_391@elavil/Receiver from test_390@elavil/Sender: Socket Error to Client But I have nothing in s.test_390, which contains stderr from my test_390 sending client: [dpuryear@zoloft dpuryear]$ ll s.test_390 -rw-r--r--1 dpuryear dpuryear0 Aug 16 13:16 s.test_390 So sometimes bounces get through, and sometimes not? Not sure what is going on. BTW, I ran jabberd on another machine and swapped the client machines and get similar results. Temas, thoughts? I archived all of the data from this test, including the jabberd log files. Let me know if you want them.

re: bounces
Bounces? Maybe, but I don't see how. My test programs send from user A
to user B, and I always know who user B is since it's hardcoded into the
testing applications (more or less).
The code is pretty short: msgloadsnd and msgloadrec are each about 500

It is always possible I did something stupid.

I have multiple user pairs, where each pair is composed of a sending
client A and receiving client B. Under a high load not all messages sent
from A appear to arrive at B. I find this odd because I would think that
the delivery time would be the only thing affected under high load, not
actual message delivery. Thus, I suspect my code, but can't rule out
jabberd.

Notice that at = 120 user pairs (240 connected users), which equates to
120 msg/sec in this test, my message loss rate varies from 3% to 13%.
The average delivery also climbs to .14 seconds, but I don't consider
that a problem. (However, the worst case delivery times are bad: 6
seconds for 150 and 160 user pairs.)
There are only two places that I feel messages could be getting lost: in
jabberd and in msgloadrec, the receiving client. If it's in jabberd then
I have to wonder why this is happening. If in msgloadrec, I'm also a bit
bewildered.
Perhaps I am not handling my XML parsing correctly with expat? My XML
character data handler is:
void char_data_hdlr(void *userdata, const XML_Char *s, int len)
{
user_data_t *ud = userdata;
char buf[MAX_XML_BUFSZ+1];
struct timeval tv;
reply_data_t *reply;
int id;
memcpy(buf, s, len);
buf[len] = '\0';
DPRINT(found message: %s\n, buf);
/* scan for our start times at the beginning of the message */
if (sscanf(buf, %d %ld %ld ,
id, (tv.tv_sec), (tv.tv_usec)) == 3)
{
reply = malloc(sizeof(reply_data_t));
if (reply == NULL)
{
perror(malloc());
exit(EXIT_FAILURE);
}
DPRINT(char_data_hdlr(): adding buf = %s with sec = %ld and usec =
%ld\n,
buf, tv.tv_sec, tv.tv_usec);
reply-begin.tv_sec = tv.tv_sec;
reply-begin.tv_usec = tv.tv_usec;
reply-id = id;
list_add((ud-reply_list), (void *) reply);
}
}
All character data has the form: decimal float float. Hmm, should I
not be assuming that I will get the entire character data at once?
Perhaps it is being split across multiple invocations of
char_data_hdlr() by expat? Any ideas?

If so then any application that requires all messages to be delivered will have to include some type of ACK feature.. I would think. bounce is happening and it is actually getting lost somehow. It has high priority in my books, but I need info, debug logs, incoming/outgoing XML for both parties involved, and anything else that will help. I can do this. Note however that jabberd has to be under a high load for the problem to occur. That means you can expect _a lot_ of debug and log data. Perhaps you would like to run the test suite on a personal test box? It may be easier for you to see what data you need? Otherwise you can expect a 50MB email from me. :) Hmm, a while ago a guy from the OSDN asked for developer access to the testing tools.

We've just developed a project (client+server) for one of the biggest ISP in Italy. We found since the beginning that each Jabber server was not able to handle more than a couple hundreds client, so we implemented an architecture that load balances the traffic among many concurrent servers running on the same or different hosts. We also encountered message losses, but we didn't care much :-). As Dustin, we thought this was due to client problems. Well, now that I know someone else has had a similar experience I can only assume the problem is with jabberd. I had hoped that jabber.org would confirm this to either be a problem or something they had built into jabberd, but that information hasn't been very forthcoming. In the end I suppose developers using jabberd need to realize that it only works in low to medium load environments where message delivery is not a big issue. Unfortunately, I am not sure if the same is true of the jabber.com server since they didn't present any information on this topic either.

[JDEV] re: dropped messages
re: jabberd seems to be dropping messages under a high load I had another developer at Vedalabs review my Jabber Test Suite code to ensure that I was properly handling the XML in msgloadrec. We seem pretty confident that I am not losing messages on my end, which indicates that either Linux or jabberd is dropping entire messages going from the sender to the receiver on the Jabber server when the machine is under a high load. As I mentioned in my first post I had expected message delivery time to increase rather than a flat-out dropping of messages. Is this or is this not known, correct behavior? Can I get a confirmation from someone on the Jabber.org or Jabber.com team? As of right now we get a rate of 100 msg/sec through jabberd on a Pentium III 600 before the loss rate becomes unacceptable (greater than 2%). Is this outcome similar to anyone elses situation? Has anyone else tested how jabberd or jabberd/Linux behave under high loads? What is the expected behavior? If you are building clients to use Jabber for routing messages how are you handling this? Do your sending Jabber clients require ACKs from your receiving Jabber clients? (Well, obviously this isn't a serious situation for chat clients, but it probably is for most other types.) Jabber.com, we have numbers from you regarding limits on concurrent users, but what about message throughput rates? Can we get some information?

[JDEV] dropped messages?
I am trying to determine why messages appear to be dropped when jabberd
is under a heavy load. I'm not sure if it's my code or jabberd, so I'm
looking for ideas.
I have multiple user pairs, where each pair is composed of a sending
client A and receiving client B. Under a high load not all messages sent
from A appear to arrive at B. I find this odd because I would think that
the delivery time would be the only thing affected under high load, not
actual message delivery. Thus, I suspect my code, but can't rule out
jabberd.
Following are Jabber Test Suite results generating my concern, and then
a review of what is going on:

1601 60 0.015396.239720.147958280 9600 0.13750
Notice that at = 120 user pairs (240 connected users), which equates to
120 msg/sec in this test, my message loss rate varies from 3% to 13%.
The average delivery also climbs to .14 seconds, but I don't consider
that a problem. (However, the worst case delivery times are bad: 6
seconds for 150 and 160 user pairs.)
There are only two places that I feel messages could be getting lost: in
jabberd and in msgloadrec, the receiving client. If it's in jabberd then
I have to wonder why this is happening. If in msgloadrec, I'm also a bit
bewildered.
Perhaps I am not handling my XML parsing correctly with expat? My XML
character data handler is:
void char_data_hdlr(void *userdata, const XML_Char *s, int len)
{
user_data_t *ud = userdata;
char buf[MAX_XML_BUFSZ+1];
struct timeval tv;
reply_data_t *reply;
int id;
memcpy(buf, s, len);
buf[len] = '\0';
DPRINT(found message: %s\n, buf);
/* scan for our start times at the beginning of the message */
if (sscanf(buf, %d %ld %ld ,
id, (tv.tv_sec), (tv.tv_usec)) == 3)
{
reply = malloc(sizeof(reply_data_t));
if (reply == NULL)
{
perror(malloc());
exit(EXIT_FAILURE);
}
DPRINT(char_data_hdlr(): adding buf = %s with sec = %ld and usec =
%ld\n,
buf, tv.tv_sec, tv.tv_usec);
reply-begin.tv_sec = tv.tv_sec;
reply-begin.tv_usec = tv.tv_usec;
reply-id = id;
list_add((ud-reply_list), (void *) reply);
}
}
All character data has the form: decimal float float. Hmm, should I
not be assuming that I will get the entire character data at once?
Perhaps it is being split across multiple invocations of
char_data_hdlr() by expat? Any ideas?

[JDEV] testing tools
I've made a few changes to the testing suite. One affects performance of the tools on the clients. In addition, I recently added nusers2.sh, which automates the testing of testing n clients on two hosts passing x messages per second for t seconds. It will also invoke sar on the Jabber server if possible. As always you can grab the testing suite's source code at http://www.sf.net/projects/jabbertest. If you want the binaries then email me. Note that I will send you binaries compiled with the expat library, so each binary will be about 1MB.

[JDEV] testing tools
I had a few spare minutes the past couple of days so I made some pretty significant changes to the Jabber testing tools if you are interesting in taking a look. I removed msgblast and replaced with msgload. msgload separates the sending and receiving client, which lets the test take place across multiple clients easily (or the same one), as well as being able to specify multiple users. In addition, by using the throttling code you can easily test n users sending x messages per second, which can be used to build an effective testing framework (ie., server load or karma settings). If you are using active_jab (an unsupported prototype for the project) you may want to drop it and try the new release. You can retrieve via CVS, and I may release a tarball with the binaries sometime today or tomorrow on the site. Until then you can email me and I'll send you a tarball of the tools. Currently included are: msgload - message load testing pasvlogin - login testing, simple and digest based userreg - user registration speed http://www.sf.net/projects/jabbertest Note: for obvious reasons if you are using msgload across machines and printing out the timing data your clocks need to be synced.

Re: [JDEV] [jadmin] performance numbers.. questions
Ignore the email below.. mail client problems. Regards, Dustin Dustin Puryear wrote: I am actually now getting some hard numbers from the jabbertest tools. One test I ran connected 1000 users to a Jabber server running on a Pentium III 600 with 192MB of RAM. I saw some odd results. But first, here is how the test works: active_jab basically connects 1..n users serially, and sends x messages when each user connects. It does NOT send messages concurrently for each connected user. (Although that would be an excellent feature--to be added soon!) Instead, if you want to simulate multiple users sending messages at the same time to the same server then you just run muliple instances of active_jab on the same or different client machines. (Very simple.) The basic idea is: for user 1..n do connect user to jabber send x messages and track delivery times done for user 1..n do disconnect user from jabber done Memory === First of all, I assumed that Jabber would consume a lot of memory, which turned out to be a wrong assumption. I saw my %memused jump from a rough minimum of 81% to maybe 95%. My %swpused did not change significantly, which indicates that I had enough core memory for the job. (Remember Linux always uses as much memory as it can for buffers, so the starting value of 81% isn't surprising.) The big issue here is that there was only a small jump--around 14%. CPU === Big surprise here. Jabber seems to *quickly* begin eating CPU cycles as the number of connected users increases. Here is some data: users idle user sys 0 99% 1%0% 200 70% 24% 3% 500 45% 50% 5% 800 30% 64% 6% 100020% 70% 10% (Yes, the totals may be more or less that 100%. I am getting these numbers from graphs and quickly jotting them down.) Note that Jabber is consuming 24% of the CPU at 200 users on a Pentium III 600. I also noticed that as more users are connected the message delivery time decreased. The progession was slow.. usually going from 0 seconds to 2 seconds as the number of users went from 0..1000. But still.. why is that? Remember I am not sending message concurrently. Instead, as each user connects active_jab sends x messages (defaults to 5), and then proceeds to the next user. I would like some feedback on this data. Does this look like what everyone else has been experiencing? Are my numbers out of wack?! What other numbers would be useful? I think the next logical step is to run active_jab on several machines at once. That way we can test how many *concurrent* users can connect and send messages.

Re: [JDEV] digest authentication
Max Horn wrote: Despite me using a phoney password, I know that Gabber is producing proper output since I can login using the correct password. Ah!

The hash element in Gabber's output is for the 0k-auth mechansim For more information on digest-auth, check out http://docs.jabber.org/proto/html/jabber:iq:auth.html For more information on 0k-auth, check out http://docs.jabber.org/draft-proto/html/zerok.html Well darn. I was reading strictly from Protocol - Standard:Simple Client Authentication (which, oddly enough, includes both simple and digest client authentication--shouldn't this be renamed Client Authentication). Since Jabber is relatively new I suppose I need to delve into Protocol - Draft more often. So.. what I am doing is correct then. I am taking the session ID, concatenating the password to it, passing it to shahash(), and I should use that as the digest value. Ok then. Thanks Max.

[JDEV] test suite
The original release of the test suite was a working prototype. Naturally, I have scratched it and am now building the suite proper. Please feel free to check it out from CVS and make contributes, test the code, or just use it. Currently, I only have a working version of msgblast (send as many messages as possible and time return delivery for ONE user) in CVS. I have the following remaining to complete: 1 message delivery with x logged-on passive users 2 message delivery with x logged-on active users 3 user creation time 4 roster request time 5 authentication time for given authentication method 6 filters? Colin, the 'max users before message latency becomes noticable' and 'max registered users before auth process takes too long' of your request doc are obviously covered by 1, 2, and 5. Oh, the snapshot release on SourceForge is NOT updated. I need to figure out how to automated the process on SourceForge at some point. So for now it's only CVS.

[JDEV] using dpsm..
Okay, one more question about dpsm. I have removed the c2s section in jabber.xml and replaced it with: service id='dpsm' accept ip/ port5225/port secretdp5m/secret /accept /service I then try and run dpsm, but get the error: Starting up... configure()... init()... Could not create connection to jabberd ?xml version='1.0'?stream:stream xmlns:stream='http://etherx.jabber.org/streams' id='3B02E9D4' xmlns='jabber:component:accept' to='dpsm' Ok.. so dpsm can't connect to jabberd apparently.

[JDEV] performance numbers.. questions
I am actually now getting some hard numbers from the jabbertest tools. One test I ran connected 1000 users to a Jabber server running on a Pentium III 600 with 192MB of RAM. I saw some odd results. But first, here is how the test works: active_jab basically connects 1..n users serially, and sends x messages when each user connects. It does NOT send messages concurrently for each connected user. (Although that would be an excellent feature--to be added soon!) Instead, if you want to simulate multiple users sending messages at the same time to the same server then you just run muliple instances of active_jab on the same or different client machines. (Very simple.) The basic idea is: for user 1..n do connect user to jabber send x messages and track delivery times done for user 1..n do disconnect user from jabber done Memory === First of all, I assumed that Jabber would consume a lot of memory, which turned out to be a wrong assumption. I saw my %memused jump from a rough minimum of 81% to maybe 95%. My %swpused did not change significantly, which indicates that I had enough core memory for the job. (Remember Linux always uses as much memory as it can for buffers, so the starting value of 81% isn't surprising.) The big issue here is that there was only a small jump--around 14%. CPU === Big surprise here. Jabber seems to *quickly* begin eating CPU cycles as the number of connected users increases. Here is some data: users idle user sys 0 99% 1%0% 200 70% 24% 3% 500 45% 50% 5% 800 30% 64% 6% 100020% 70% 10% (Yes, the totals may be more or less that 100%. I am getting these numbers from graphs and quickly jotting them down.) Note that Jabber is consuming 24% of the CPU at 200 users on a Pentium III 600. I also noticed that as more users are connected the message delivery time decreased. The progession was slow.. usually going from 0 seconds to 2 seconds as the number of users went from 0..1000. But still.. why is that? Remember I am not sending message concurrently. Instead, as each user connects active_jab sends x messages (defaults to 5), and then proceeds to the next user. I would like some feedback on this data. Does this look like what everyone else has been experiencing? Are my numbers out of wack?! What other numbers would be useful?

[JDEV] test suite released as tarball
You can now download and use the Jabber test suite without using CVS. Simply download the tarball located at http://www.sourceforge.net/projects/jabbertest. Note that there is a script named run_test.sh that will run sar on the Jabber server and run active_jab, the primary testing tool, locally. It will then collect the remote sar stats. If you do not have sar download sysstats for Linux or build your own scripts to use vmstat and so forth. Also, the tool uses ssh, but you can easily replace with rsh if you are insane enough to use it. You do NOT have to be able to use run_test.sh to use the package. You can easily run active_jab alone if that is adequate for your task. Finally, there is a limited README included that should give a overview of how to use the package.

DJ Adams wrote: logins (may need less, but I am only using second-resolution at this point) or I get errors. Also, I ended ripping out the karma code in Could this be the rate/ ? Doesn't seem to affect it. Also, I am experiencing problems even with the default rate setting: rate points=5 time=25/ What happens is that _usually_ by the third time I open a stream and start sending data Jabber does NOT send the messages I send back to me. I just use a select() to time-out after a second or so in order to abort a read(), which would just hang. If I introduce a 1-second delay (maybe shorter, but this is the value I'm using now) then I have no problems. I can connect X times and each message I send is sent back to me. You can see the problem by running active_jab, from the test suite, as: $ ./active_jab -s localhost -j crack -t 5 This produces the time-outs. If I use: $ ./active_jab -s localhost -j crack -t 5 -w 1 Then I get no time-outs. Anyone have any suggestions?

Re: [JDEV] register then reconnect?
Peter Saint-Andre wrote: Yes, the stream/ basically defines the session, so registering a new user would be starting a new stream. That doesn't seem very logical to me. A stream should be independent of a session, especially if you define a session (I really need to read all of the Jabber docs) as a set of events that occur for a given task. Say, to add a user. Or to authenticate and then message others. It seems like I should be able to actually have multiple sessions on one stream by simply leaving the stream open: open stream add user add user authenticate as user a message message chat logoff authenticate as user b message message chat logoff add user close stream Of course, if we are closing an authenticate session by closing the stream it would be different: open stream add user add user authenticate message message chat close stream I can see the advantage to the first method however in that you could begin to 'cache' your connections client side for a large site and reduce the need to open and close connections, which can be expensive for both parties. You may even be able to pool sessions on one stream at some point. Regards, Dustin Peter Dustin Puryear wrote: I am working with a very simple Jabber client.
