[users@httpd] Dynamic load balancing and Rules based processing.
Hi All, What are the approaches need to be taken for dynamic load balancing.Like suppose I have 3 instances of Apache is running and due to some issue one of the instance goes down.I would expect the traffic should be balanced properly by the existing 2 instances. For load balancing apart from mod_proxy_balancer any other Apache modules can be worth looking into? Any functionality in Apache based on Rules ? Comments and suggestions would be very much appreciated. Thanks in advance, -A
Re: [users@httpd] Need information about using Apache....
Can I use Apache instead of Drools? Like as a rules execution engine that is able to accept the request, evaluate a set of ops defined rules and execute various responses. Mod_proxy and mod_proxybalancer does the load balancing.Is there anything can be done where each instance can hve own functionality like one instance may be tracking the IP, another instance may be tracking by GUID or Screenname, and yet another may be tracking by some Signature ? Should I follow the worker model where each process launches threads and threads have the logic ?

[users@httpd] Need information about using Apache....
Dear All, We are planning for an enhancement of our servers.We are looking out if we write Apache module and use Apache to support the below requirements. We would like to use Apache as a routing layer that accepts both structured documents (XML docs) also some other predefined data blocks in addition to key/value paris via http and then routes those transactions based on a key available in the request such that the required keys and sub keys are all routed to the same rules instance - this will require the original request to be broadcast to multiple instances of the rules engine ( for example, one instance may be tracking the IP, another instance may be tracking by GUID or Screenname, and yet another may be tracking by some Signature.) A rules execution engine that is able to accept the request, evaluate a set of ops defined rules and execute various responses. There are preference of using DROOLS fusion. As and alert broadcast engine that has the ability to distribute an events to multiple end sources. As a storage layer that allows for data persistence for long term tracking of keys and values. Inputs would be very much appreciated. Many thanks in advance -A

Re: [us...@httpd] using mod_custom_header module.
We are using Netscaler VIP.So when a request comes instead of Client IP it puts its own IP and forwarded the request to the backend. We do have the option to use X-Forarded-For but again it appends the different hops to it.We want the IP adress from where the request has come to Netscaler.So we would like to get that particular ip address.So wondering if we can use mod_custom_header module in this case?

[us...@httpd] getting client ip address information from http request.
Hi All,
How do I retrieve client ip information from the http request in Apache
module ? Like the loadbalancer is putting it own ip in the place of client
ip address. We tried %{X-Forwarded-For} but this takes care of access log
not the module specific log.
So from the request is there any function call can be done to retrieve the
client information.
Thanks in advance.

They have some internal benchmarks that appear to back this up, but, being a natural skeptic, I wanted to test it out for myself. So I've agreed to pit Apache and LiteSpeed (as well as a few other webservers) against one another in benchmarking tests on a 2x Xeon 5520 machine. I, and hopefully others, will be configuring Apache. LiteSpeed will be configuring their product. What is the workload you are benchmarking? Static pages, PHP/mod_perl code, CGI, etc.? Is the client a benchmark tool or a browser, and where on the network is it relative to the server? How are you measuring performance (page load times, requests/second, etc.)? -Scott. Scott, I'm open to suggestions on all fronts, but as it stands we were going to do the following with the ab tool: -small static pages test -large static pages test -hello world php test And we were going to also benchmark a wordpress/joomla site in a more real-world load simulation test using the tool siege. For smaller static content that will be fetched multiple times without changing, consider mod_mem_cache, which will avoid most disk I/O for that content. For larger content or content that will just be fetched once or change frequently, consider enabling sendfile or mmap for sending it. For PHP, use a PHP accelerator, such as eAccelerator, APC, or Zend. For larger applications, do your best to configure the different components appropriately, for example with Drupal configure the static Javascript and CSS files to be cached with mod_mem_cache, use the PHP accelerator for the code, and if you have any large files make sure you have sendfile or mmap available. If the benchmark client will do any caching, make sure expiration is configured to allow a long cache time. Disable .htaccess unless you need it, so Apache doesn't have to look for it. Do a dry run while running top and iostat to see where your bottleneck is. Try running Apache under strace to see what it's doing at each request, and get it doing as little as possible. If it is serving a file from the memory cache or with a static mmap, strace should show it making practically no system calls. If you google around for Apache benchmark tuning I'm sure you'll find some other ideas and examples. Good luck! Scott.
[us...@httpd] Help on KeepAlive
Hi All, One help is regarding KeepAlive directive. I am using Apache as a pipe.It gets client request and just forwards the same request to another module. We use Apache 2.2 Worker Model in Linux.These client request traffic is high and data is dynamic (content length is dynamic). We have made KeepAlive Off as per Apache, it is more useful for static contents, it is going to reuse the TCP/IP connection and the connections are going to be open longer time These inputs are there in the Apache doc of 2.2. The system is running perfectly for a long time. I would like to know in real if we keep KeepAlive On what would be the behavior is going to be observed when the Client request is very much dynamic. Note here Apache is not used for serving pages. Thanks in advance. -A

Hi, Can you try with Non-zero MaxRequestPerChild value.Keep a value which is equal to number of request are particular process you want to handle.Once it is done the process will be killed and a new process is going to be started.I guess your CPU usage should come down.

[EMAIL PROTECTED] Help on Apache pause
Hi All, Is there anyway to check Apache closing the sockets properly? I am getting lots of CLOSE_WAIT ,SYNC_RCV and TIME_WAIT state when I do a netstat -a, and result it is Apache pauses.It waits for sometime and again it comeback for processing.I did tried changing some of the TCP stack param tcp_keepalive_intvl,tcp_keepalive_probes ,net.ipv4.tcp_max_syn_backlog,net.ipv4.tcp_synack_retries, net.ipv4.tcp_fin_timeout but still the problem is reproducible.This happens under heavy load only.

[EMAIL PROTECTED] question on TIME_WAIT

[EMAIL PROTECTED] Apache and lingering close

What would be the ideal approach to solve the issue.I am planning for explicit call of ap_lingering_close after reading the client request. Also I see a #ifdef CORE_PRIVATE under httpd_connection.h where ap_lingering_close is defined and the macro #define CORE_PRIVATE is defined in mod_proxy.h.But I don't use mod_proxy so is it going to impact anything? For TIME_WAIT plan to reduce tcp_max_tw_buckets value.Is it going to be impacted? For SYNC_RCV Increasing net.ipv4.tcp_max_syn_backlog, decreasing tcp_synack_retries and enabling tcp_syncookies.

Re: [EMAIL PROTECTED] too many open files
Hi Michael, Did you tried the following ulimit -S -n `ulimit -H -n` ? This will assign the max open file hard limits value to your soft limit. Can you check the output of ulimit -H -n and ulimit -S -n?Former gives your hard and the latter gives your soft limits respectively. Even if the above step is giving problem then increase the hard limit to max value as per ur system should be something like 99.So put this value to ur soft limit by the above procedure in the apachectl script and try out.You print the value of ulimit -S -n in you apachectl script just to make sure the change is taking place.Make sure the shell which runs the apachectl gets the incremented FDS.

Hi All, My query is , in apache access_log we get the entry of 127.0.0.1 - frank [10/Oct/2000:13:55:36 -0700] GET /apache_pb.gif HTTP/1.0 200 2326 What the log document says is 10/Oct/2000:13:55:36 is the time when the request is received by Apache.So suppose the server is overloaded and it has a ListenBackLog 511, so if the request is in queue does apache starts the timer or the timer is started only when it is fetched from the queue.Also my guess suppose the request is not in queue so the timer is going to be started immediately.Please let me know your views.

[EMAIL PROTECTED] Nonexistent process in Red-hat 4.0
Hi All, I am getting a interesting problem.I have a module build on Red-hat 3.0.I am using Apache2.2 MPM model as Worker. Now I print the current process id in my logs whenever I get my any request. In 3.0 the process ids are matching with what exactly the Apache launches.But when I move to 4.0 the process id doesn't match at all.Logs are printing the same process id.And if I do a ps -aef|httpd on that process id I get no such process exists.Also if I try to kill that processI get the same statement as No such process.But functionality of the process is fine. Not sure as this is the correct forum or not.If you have come accross this sort of problem please let me know. Thanks in advance. Regards -A

[EMAIL PROTECTED] File descriptors in Solaris and Apache
Hi, I have seen the apachectl script assigns the max open files of hard limit to soft limit. Now suppose if we consider the Solaris OS wihout having the library /usr/lib/extendedFILE.so.1 ,the max open files is 256 even if it is increased from /etc/system. So how does the Apache will take care of this if it tries to open more than 256 file descriptors ? Thanks in advance for help. Regards -A
[EMAIL PROTECTED] Memory leak in Apache?
Hi All, I was referring to http://httpd.apache.org/docs/2.0/misc/perf-tuning.html and the below paragraph is a snippet from the given url I am not clear about the which memory leaks it is referring.I have highlighted that part. Related to process creation is process death induced by the MaxRequestsPerChildhttp://httpd.apache.org/docs/2.0/mod/mpm_common.html#maxrequestsperchildsetting. By default this is 0, which means that there is no limit to the number of requests handled per child. If your configuration currently has this set to some very low number, such as 30, you may want to bump this up significantly. If you are running SunOS or an old version of Solaris, limit this to 1 or so because of memory leaks. Can somebody explain me the above memory leaks?Is it fixed in the Apache2.2onwards release, also in case of Linux OS do we need to follow the same procedure as that of SunOS for the param MaxRequestPerChild. Thanks in advance. -A

Hi, you can do df -k on the logs dir where Apache was writingI guess the disk usage was full for that particular dir...Next time when you get into similar issue it is worth to check this.

First i thought about problems with logrotate, but logrotate runs at 4.15 am, and logging stopped at 16.28 pm. I'm sure that logging stopped, because i have a tool running on another box checking this webserver every 2 minutes, and informing me via email if it's not running any longer. This tool did not inform me. Of course this tool creates every two minutes an entry in access_log. And these entries i'm missing, and surely others. The OS is a SuSE 9.2.

Re: [EMAIL PROTECTED] Memory usage in Apache
Hi, What my observation is, intialy the memory consumption is increased but after sometime it remains same.Also the memory consumption by the active daemon doesn't comes down even there is no processing of request.All the above things happen only when I keep the MaxRequestperchild to 0. My next question is I hve kept the ServerLimit and StartServers as 1 but once the Apache runs for say around 20hrs with good traffic, it still launches one more daemon process...Why this behavior is happening I am not sure. The modules that I have loaded are the cgi module, server-status module and mod_authz_host module.Does this have any impact one the above behaviors? Thanks in advance.

I don't believe there are any known memory leaks in apache httpd. But it wouldn't be unusual for memory usage to increase somewhat over time since some requests require more memory than others and it is usually impossible to return memory to the OS. It shouldn't continue to rise indefinitely. Memory leaks might be present in some module that you using with apache. You can, of course, recycle processes occasionally by setting MaxRequestsPerChild to some not-too-small number. Other than that, I'm not sure what question you are really asking.
