PNP4Nagios has a feature called pages that allows you to show multiple

I can't seem to get the pages feature of pnp4nagios working
correctly to get an assembly of charts.
I just tried creating a page by modifying the canned file
web_traffic.cfg-sample in the directory /nagios/etc/pnp/pages/
like so:
filename: cpu_temperatures.cfg #
define page {
use_regex 1
page_name Compute Nodes Current CPU Core Temperatures
}
define graph {
host_name star177,star178,star179
service_descCpuCoreTemperature
}
I still do not see the webpage. Where should I be looking for in the
web-interface?
I already have a corresponding entry in the services.cfg file:
define service{
use rpn_intermediate_service
hostgroup_name 64bit-compute-nodes
service_description CpuCoreTemperature
check_command check_nrpe!check_cpu_temp
use srv-pnp-rpn-intermediate
}
The permissions and ownership of cpu_temperatures.cfg also seems
correct. What else could I be messing up? Any advice?

[Nagios-users] how can I access data stored by pnp4nagios
I just updated my nagios installation so that I can get cpu-core temperatures with lm_sensors. Works fine. I have pnp4nagios which give good time series trends of temperatures as well. But the problem is if I want a snapshot of CPU temperatures right now for my whole server room hardware (or at any other past instance of time) pnp4nagios is not useful. It gives a time series but not a spatial (trend over servers at a point in time) graph. If I wanted to hack together my own graphing tool what's the best place to pull out data from? Digging in I noticed the /nagios/share/perfdata/serverxxx/ directory which does have the xml and rrd files. Is this a good spot to pull data out from for each monitored server? Unfortunately that would only be for the latest time instance , right? But since pnp4nagios can plot over a time range it must have access to historic temperatures too. So, where are these stored? I suspect internally as a binary produced my rrdtool? In which case is there another way for me to access historic_perf_quantity at a given point in time for all servers? Or perhaps it is possible to generate something like this using custom rrdtool queries?

Databases need management and tuning to get you good performance - that's just routine, regardless of the brand you are using: mysql, SQL Server, Oracle, Postgres, But the way nagios natively stores data seems to be pretty robust though. Nagios has scaled excellently right out of the box. From all these discussions it seems that the problems arise when I try to hook up ndoutils etc. in there. Maybe I am wrong! No amount of work or polishing will change that. There's a reason DBAs are highly valued professionals. I feel that's the crux though.

[Nagios-users] graphing trends across hosts or services instead of a timeseries
One other thing that I haven't figured out yet with PNP-NAGIOS is this: How does one get trending across services or hosts? i.e. It is easy to see time series graphs of pingtimes, load averages disk usages etc. but sometimes what seems more relevant is a chart across services for a given snapshot in time. Say, to identify a hot node, or a node with unusually high load averages. Is there a way to do this?

[Nagios-users] how is Service check Latency defined in nagios?
What exactly is the Service check Latency in nagios? My processor load averages are still ok after I enabled PNP but my latencies have shot through the roof. Should I be worried or not?

I have: max_concurrent_checks=0 Our experience has been that with max_concurrent_checks set to 0 and inter-check delay and nagios sleep set very low we get high reported service check latencies as we are basically asking Nagios to try and run everything as soon as possible ... 1000s of checks over a few seconds in essence ... which it can't do. As far as 'real life' negative impact the high latency in this singular case hasn't meant much; it initially really worried me until i realized that the high service latency is just happening because we are basically telling nagios to pause / sleep / wait for as little time as possible and run things as quickly as possible. We have around a 146 second service check latency but from our detailed Nagios metrics we see that check runs are completing in right around 4 minutes, under our 5 minute hard-ceiling (around 6000 checks). our PNP performance graphs prove our suspicions .. our reporting server receives 6000 metrics in 4 minutes or less and we have no gaps in our graphs or major under or over sampling problems with the data we retrieve from our remote agents. I only bring that up because if you not only have max_concurrent_checks set to 0 but also have tuned way down inter-check delay settings and sleep time you might be encountering the same situation and the high latency might not be something to worry about .. but only IF you have all your delays tuned very low and no ceiling on max checks. for any other situation it is definitely something to investigate.

Suddenly it goes as high as 54 and then for a while it owns only 3 processes. Then it shoots up again. Very interesting. Maybe that is the phenomenon you were referring to?

[Nagios-users] NRPE and redundant calls to remote hosts.
I've been adding a bunch of checks via NRPE on remote nodes and this got me thinking. Isn't it inefficient to keep starting check_nrpe calls from the monitoring host all the time? Why cannot nrpe on the remote node monitor some of the local services and only send a message back to nagios if there is a status change? For warnings based on things like disk usage, cpu usage, total procs, pbs scheduler daemon status , cpu temperatures etc. coudn't this approach relive the central host's cpu of a lot of endless check_nrpe calls? NRPE is already doing the work; its just a question of what initiates a communication channel between NRPE and nagios. Just curious.

I was just using the example from the nagios tutorial for now. Maybe its alive/dead status ; bandwidth of individual ports (but that's mrtg's job right?) ; dropped packets; some thermal events? How does one go about this? What are other users montoring on their switches and how does one go about translating the fairly cryptic SNMP fields into something usable? Should I dig into my Dell switch manuals? Or is this reinventing the wheel and Nagios has an automated way to achieve this already? If you are just running this for one port on one switch, then loading the MIB is no biggie, if you plan to monitor hundreds or thousands of ports, would be better to use the numeric form of the OID and run an ePN plugin using the perl Net::SNMP or NSNMP library or a plugin that implements the C Net-SNMP libraries directly The maximum I'll end up monitoring is perhaps 4 switches with 48 ports each. So from your stats this should be on the fairly low side. -- Rahul -- This SF.net email is sponsored by: SourcForge Community SourceForge wants to tell your story. http://p.sf.net/sfu/sf-spreadtheword___ Nagios-users mailing list Nagios-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/nagios-users ::: Please include Nagios version, plugin version (-v) and OS when reporting any issue. ::: Messages without supporting info will risk being sent to /dev/null

Thanks Jake! I'll heed the advice. I wasn't sure about what are the parts best worth tackling to gain efficiency. Specifically, look for any service check that takes longer than a second. Is there a place where it logs how long a service check too? How do you usually find out? I can only see when it was last checked on my interface but not how long it took. Also make sure your timeouts are set low as this can easily be a source for high load averages - e.g. if you consider 500ms latency on the ping service to be critical then why not set your timeout value to one or two seconds instead of 10 (which is the default for check_ping). Is *service_check_timeout=60 in the main config file the timeout that you are talking about? I might be mistaking what you mean.* Shouldn't this matter only for the nodes that *do* have a latency problem alone? I hope these will remain a minor fraction. But the major chunk will be the ones that respond within the timeout but still a *lot* of work. How does it work out that the timeout made such a huge difference for you?

As for ping I don't check as a service only a host check which gets executed if any service turns critical. That might be the exact functionality I was thinking of. If I look under Host Status Details for all host groups I see very recent and regular checks being done on all my hosts under the column for Last Check. Even ones that do not have any services critical. Or will I only see the behavior you describe after I somehow disable active host checks?

[Nagios-users] Ways and tweaks to make nagios more efficient. load average on monitoring host edging up.
I set up my nagios system to monitor 256 odd nodes each with about 6 services (direct and NRPE). It is working fine but my load averages have started edging upwards. Not critical yet but I wanted some tips to make things more efficient and see if there are things I might have done ineffeciently. One of the points I identified is this: I am doing a ping and ssh check on each server. This seems redundant. Is there a way to set it up so that: Do a ssh check; if this succeds obviously ping is ok. If it fails do a ping check and report on that. How about the other way around too? I have a bunch of NRPE checks: load_average, total-processes, scratch and home dir usage, pbs_mom, ntp_time. If ssh fails then there is obviously no reason to try these other checks right? But I think the monitoring_host wastes its cycles still trying them (based on the Last Check time) Any tips how I can achieve these effeciency tweaks? Or is there a problem in my strategy? Any other performance tweaks so that I can squeeze every ounce of Nagios performace? Already I am using NRPE rather than check_by_sshh since I was told the latter might be ineffecient for the monitoring host load usage. -- Rahul -- This SF.net email is sponsored by: SourcForge Community SourceForge wants to tell your story. http://p.sf.net/sfu/sf-spreadtheword___ Nagios-users mailing list Nagios-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/nagios-users ::: Please include Nagios version, plugin version (-v) and OS when reporting any issue. ::: Messages without supporting info will risk being sent to /dev/null

[Nagios-users] using NPRE to monitor pbs_mom. Error: NRPE: Unable to read output
I'm a bit confused about how exactly to add stuff with NRPE to monitor local services on my remote hosts. I got the basics out of the way and I can already monitor the easy stuff like users, procs, swap etc. More ambitiously, I wanted to monitor the status of my pbs_mom (Torque Scheduler daemon) on each node in my cluster. I found the script check_pbsmom.sh on the NagiosExchange (snippet below) and copied it to my /usr/local/nagios/libexec. Then I added this line to my nrpe.cfg command[check_pbsmom]=/usr/local/nagios/libexec/check_pbsmom But then I don't seem to have much success. remotehost/usr/local/nagios/libexec/check_nrpe -H localhost -c check_pbsmom NRPE: Unable to read output If I just run the shell script though it seems to be working /usr/local/nagios/libexec/check_pbsmom.sh PBS_MOM OK: Daemon is running. Host is listening. What am I doing wrong here! I'm still a bit confused about the interaction between command.cfg on the monitoring machine and the nrpe.cfg on the remote host.

[Nagios-users] tweaking the order of sorting in nagios lists: numeric rather than alphabetical
Is there a way to tweak the manner in which nagios sorts the names of hosts in the Service Status Details? I have hosts named star01, star02 and so on all the way through star256 and nagios insists on sortin these like so: star10 star101 star102 [snip] star119 star12 etc. Can I make the numbers sort in a numeric order rather than a strict alphabetical order? -- Rahul -- This SF.net email is sponsored by: SourcForge Community SourceForge wants to tell your story. http://p.sf.net/sfu/sf-spreadtheword___ Nagios-users mailing list Nagios-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/nagios-users ::: Please include Nagios version, plugin version (-v) and OS when reporting any issue. ::: Messages without supporting info will risk being sent to /dev/null

Why cannot an appropriately set notification-scheme directly targeting your on-call engineer work?

[Nagios-users] re-enabling check_snmp
Getting more and more impressed with Nagios's capabilities I was getting more ambitious and now was getting it to monitor the switches on my university-research-computing-cluster as well. The pings work fine but the SNMP monitoring fails. Digging deeper I noticed that I did not have the command check_snmp I think this is because when I installed Nagios two days ago I did not have snmpwalk, snmpget etc,.installed on my system. I just did a yum install net-snmp earlier today. How can I now retroactively get this check_snmp functionality? Do I have to do a ./confgure, make , make install dance again on the nagios_plugins source? That's ok but I was just afraid if it would overwrite any of my configs etc. What is the recommended procedure now? [I guess I was stupid in the fact that I skimped reading config.log in my eagerness to go ahead. I also find the ./configure has skipped on some other potentially useful plugins for me eg. mysql] I hope I am not overusing this group in my eagerness to get more done with Nagios! Apologize in advance if I did! -- Rahul -- ___ Nagios-users mailing list Nagios-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/nagios-users ::: Please include Nagios version, plugin version (-v) and OS when reporting any issue. ::: Messages without supporting info will risk being sent to /dev/null

[Nagios-users] nagios error: Could not stat() command file
When I try to access many of the sub-menu options under nagios (eg. deactivate the service etc.) I get the following error: Error: Could not stat() command file '/usr/local/nagios/var/rw/nagios.cmd'! The external command file may be missing, Nagios may not be running, and/or Nagios may not be checking external commands. An error occurred while attempting to commit your command for processing. I looked in the indicated dir and it seems empty. Should there be something in there? Does it point to a fault Nagios install? All my tests seemed OK.

[Nagios-users] Cannot add remote-linux server to my setup to be monitored
I just installed Nagios and I can monitor my localhost all right. I
tried to start with one of my remote compute-nodes but this does not
seem to work so well.
I see my new group compute-nodes on the web interface but it does
not list the remote machine I tried adding. I'm stumped as to what I
am doing wrong!
To my nagios.cfg I added this line :cfg_file=/usr/local/nagios/etc/hosts.cfg
And made a new /usr/local/nagios/etc/hosts.cfg like so:
define hostgroup{
hostgroup_name compute-nodes
alias compute-nodes
members star01
}
define host{
host_name star01
alias star01
address 11.0.0.1
hostgroups compute-nodes
check_command check-host-alive
max_check_attempts 5
check_period24x7
process_perf_data 0
retain_nonstatus_information0
contact_groups admins
notification_interval 30
notification_period 24x7
notification_optionsd,u,r
}
Shouldn't this be a basic template to get me started up? What else do
I need to do? Any debug suggestions? A ping to 11.0.0.1 is successful.
