Hi I'm wodering if it is possible to get the same webrick monitoring functionality in apache2. Doing a quick reseach on this site an goolge, I found that I can use tail -f to monitor the log realtime. But the info I need is not displayed on the access.log.
On Webrick I can see the complete request that came to the server, this includes all POST parameters that are sent to it. I'm developing a Phonegap aplication that is aiming to a production server with apache, and I need to doublecheck my REST request to the server (exactly as I did in my development environment in Rails with Webrick). That's why tail -f don't fit my needs.
Does anyone has a solution?
Thanks in advance.
I've got the solution. And it's a stupid answer. I was looking to the apache2 other_vhosts_access.log file, and the info I was getting was:
migtrace.com:80 89.131.219.51 - - [16/Sep/2013:12:14:14 +0200] "POST /api/reports.json HTTP/1.1" 200 964 "-" "curl/7.29.0"
But if I tail -f the rails production.log what I get is:
Started POST "/api/reports.json" for 89.131.219.51 at 2013-09-16 12:14:14 +0200

Completed 200 OK in 522ms (Views: 2.3ms | ActiveRecord: 259.3ms)
That is exactly what I need.

I have a strange problem in edx devstack. When I am running devstack after paver command on my localhost then I am not able to get anything on the screen once the browser screen come to loading state.
Then after a lot of time nothing is being displayed on the screen and I can see some warnings in the logs which I have attached with this que.
I have commented that code which are causing the warning message.
But after commenting warnings have gone but nothing has changed the browser again goes in loading mode and nothing happens on the screen after hitting to localhost URL,it just go in to the loading mode and nothing is being displayed.
I have also tried to run the openedx in firefox but in fore fox the links and everythings are coming but they are coming with out any style and design for the edx. I have attached a screenshot for the same.
Please help me with this issue as I am not able to figure out what to do.

Hi Guys after I posted on google group I finally got the answer. I feel like I should post this answer on stackoverflow so it is convenient for people who got stuck in their development.
1) From the screen shot it seems it is a permission issue. Give correct permission for edx-platform and themes folder if you are using any. Then try restarting the LMS and CMS and reload the page.
sudo chown -R edxapp:edxapp /edx/app/edxapp/edx-platform
sudo chown -R edxapp:edxapp /edx/app/edxapp/themes.
sudo /edx/bin/supervisorctl restart edxapp:
2) If you are able to load CMS page and LMS showing blank, may be mongodb is not running.
#mongo , if it shows some error check if swap size is full
# free -m
If swap is full, create new swap file, follow the instruction in the below link blindly.
http://www.cyberciti.biz/faq/linux-add-a-swap-file-howto/
Then try restarting mongodb, you can try restarting the system once.
I am using Red5 version 1.0.0(final release) for Java 6 on Windows XP sp3.I am using the installer version downloaded from https://code.google.com/p/red5/. I have a project wherein I am performing live webcam chats between the users. I am using RTMPT (HTTP over RTMP)protocol for that.So I have set up my Red5 server behind the Apache web server.The problem is that everything goes on well for 45-50 seconds and suddenly the RTMPT connection gets closed.I am not using a dedicated rtmpt server,i.e. I have not uncommented the rtmpt bean in the conf files.Rather I have added entries of servlet mappings(for idle,fcs,open etc) in the web.xml of my application. RTMPT is listening on 5080 port.I have tested this with previous versions of Red5 also but the problem is the same.The RTMPT connection closes after some time(within a minute).I had gone through logs but there was found nothing regarding this.Also there was no connection closure due to the inactivity period.Has it something to do with Apache? I am not sure whether server is closing the connection (though I cant find any logs about closing connection) or client closes it.Tried it out with 0.9.0 and 0.9.1 too but nothing to avail.I have heard that there were issues using RTMPT with Red5 on Mac but I am on Windows.Any pointers to this problem? Any help is appreciated.Also here are the error logs that I get on my Apache web server -
[error] (OS 10048)Only one usage of each socket address (protocol/network address/port) is normally permitted. : proxy: HTTP: attempt to connect to red5serverip:5080 (*) failed.
The same log is repeated for four times.
Here are some access logs from Apache too -
"POST /send/IDTK7NOG2PXGB/803 HTTP/1.1" 200 1
"POST /send/IDTK7NOG2PXGB/804 HTTP/1.1" 503 323
"POST /send/YXF4WTFMN8TCM/1391 HTTP/1.1" 200 8285
"POST /send/YXF4WTFMN8TCM/1392 HTTP/1.1" 200 1
"POST /send/YXF4WTFMN8TCM/1393 HTTP/1.1" 200 54
"POST /send/YXF4WTFMN8TCM/1394 HTTP/1.1" 200 1
"POST /send/YXF4WTFMN8TCM/1395 HTTP/1.1" 503 323
"POST /close/IDTK7NOG2PXGB/805 HTTP/1.1" 503 323
"POST /close/YXF4WTFMN8TCM/1396 HTTP/1.1" 503 323
Thanx!
Probably you are running out of tcp ports. A tcp connection will remain 4 minutes in the TIME_WAIT state by default, even if it is already closed. When your RTMPT stream uses 5 connections each second, your system will need at least 5*60*4=1200 ports for each connected user.
Often the firewall is limiting the amount of ports available. You can also decrease the keep-alive time of a tcp socket. If you google around with your apache error message you will find enough info to sort this out.
Your red5 server may be crashed. This occurs when your RAM usage is getting over. In that case you need to manually start red5 again. If this solved your problem, you need to upgrade your RAM. I am using about 8GB RAM after facing this problem several times. Because red5 was written using JAVA, it lacks memory. FFMPEG is good to use in a low memory. But I don't know how to provide chat using ffmpeg, exactly.
The 503 means that the service did not respond; if you are forwarding to red5 via apache, then this means there is a problem there. I would suggest not using the stand alone rtmpt bean; instead use only the servlet and remove apache from the mix to debug the issue.
My client is using Unleashedsoftware.com to connect to a Magento Store. But it gives this error.

When browsing http://www.domain.com/index.php/api/v2_soap/index/ Firebug gives me “500 Internal Service Error”.
When I browse http://www.domain.com/index.php/api/v2_soap/index/wsdl/1/, I am getting valid XML data.
I checked the server log files and it seems like:
[Thu Aug 30 22:22:25 2012] [warn] [client 92.92.92.92] mod_fcgid: stderr: in /home/doaminuser/public_html/lib/Zend/Soap/Server.php on line 762
I been searching for couple of days now and today I tried to duplicate the entire site to another test server, and it seems to be working! So that seems to be a server issue.
Please, anybody got any idea what could be the issue?
Is there any better way of debugging this issue, any sample code or debugging tips.
Magento version is 1.6.2
Thank you.
There's lots of times where Magento's SOAP API fails due to problems your Magento server has communicating with itself.
That is, PHP's SOAP implementation requires that the SOAP server itself fetch the WSDL file via http, and a local network configuration issue gets in the way of Magento fetching it's own WSDL.
You can debug this by SSHing into your Magento server, and running the following command
curl -l 'http://www.example.com/index.php/api/v2_soap/index/wsdl/1/' > /tmp/wsdl.xml
and then examining the wsdl.xml file. Because you're performing this from your web-server, you may get different results than when you're performing it from your local browser.
I had a similar problem when calling the URL
http://www.store.com/index.php/api/v2_soap/?wsdl
After some time I received the message 500 - Internal Server Error and a Premature end of script headers message in the apache error log.
After a whole day of research I figured out, that the Timeout-Directive of the Apache module (configured in httpd.conf on a Linux environment) was set to "20" which caused the server to send the 500 error after 20 seconds. The problem is, that in my case the Magento system needs a longer time to "crawl" through all wsdl.xml files in order to build the WSDL-output (if you are using Magento SOAPv2).
Maybe you should check your Timeout Directive..hope that helps.
"I have memories of this. What worked for me was to put the hostname
in /etc/hosts on the server plus the www alias on 127.0.0.1 However,
in this instance the server was in the building rather than in some
ISP place and the LAN had Windows computers on it. Windows users had
downloaded lots of trojan-virus-porn things that were spending the
whole time spamming the network so the real problem was with the
Windows computers on the network, not with the server or with Magento.
After fdisking the PC's the problem was solved."
Thank You I've been struggling for 2 days with this on magento 1.6 and Windows Server 2008 adding this line to the hosts file (C:\Windows\System32\drivers\etc) solved the issue for me:
127.0.0.1 www.Domain.com
also remember to fix your magento soap (role) because the Roles Resources doesn't save in 1.6 unless you fix this file:
MagentoRoot\app\code\core\Mage\Adminhtml\Block\Api\Tab\Rolesedit.php
replace this:
if (array_key_exists(strtolower($item->getResource_id()), $resources) && $item->getPermission() == 'allow') {
with this:
if (array_key_exists(strtolower($item->getResource_id()), $resources) && $item->getApiPermission() == 'allow') {
In my case the issue was the Mod_Security rule "PHP Easter Egg Access" was enabled.
Rule ID: 380800
Once disabled, the api access worked.
An indicator was in the Apache log file:
Jun 19 09:15:52 httpd[1024961]: [error] [client xyz.xyz.xyz.xyz] ModSecurity: [file "/usr/local/apache/conf/modsec/99_asl_jitp.conf"] [line "116"] [id "380800"] [rev "1"] [msg "Atomicorp.com WAF Rules - Virtual Just In Time Patch: PHP Easter Egg Access"] [data "phpe9568f35-d428-11d2-a769-00aa001acf42"] [severity "CRITICAL"] Access denied with code 403 (phase 2).

For those wanting a quick test script to replicate the issue (useful when trying to convince your hosting provider that it's a problem on their end), use:
<?php
$server = new SoapServer("http://<url to your magento shop>/index.php/api/v2_soap/index/wsdl/1/");
?>
This is the line in /lib/Zend/Soap/Server.php that triggers the error.
In my case if you browsed to:
http://< url to your magento shop >/index.php/api/v2_soap/index/wsdl/1/
the xml was fine, but if you ran the above php script on the server, the error was given.
This error most often appeared for me while omitting www for domain given in Magento SOAP url. Url has to match base url specified in the Magento config.
Currently we have an Apache 2.2.3 server with mod_ssl 2.2.3 running Django, with users authenticating by using a x509 certificate.
So far the system is running perfectly except for a single user, who when trying to upload a file receives 400 Bad Request error, and the contents of the ssl_error_log regarding this operation are:
[<date>] [error] [client <client ip>] request failed: error reading the headers, referer: <referrer url>
The contents of the ssl_access_log are:
<client ip> - - [<date>] "POST <target page> HTTP/1.1" 400 321
Also, the user's browser is Firefox as far as I know.
I am completely unable to reproduce this bug and so far none of the other users have experienced it. Could you point out some reasons for this to happen?
I've experienced connectivity that stops the upstream after an X amount of bytes is sent. X was a pretty low value, as in enough to request some simple pages, but not to deal with ajax requests much less upload files. As far as I recall, this connectivity problem occurred only when tethering (from a specific Android phone, but I didnt even test other phones).
So if the upstream gets interrupted and the upload stalls, it makes sense apache would return this error, according to this post: "Apache waits a time equal to the Timeout directive (defaults to 5 minutes if not defined) for a response from the client. It is likely Apache is waiting for the CRLF that indicates the end of the headers, yet it is never received.."
My Heroku app has crashed, and all i'm getting out of the logs is Error H10 (App crashed)
2012-03-28T14:11:56+00:00 heroku[router]: Error H10 (App crashed) -> GET www.devsite.com/ dyno= queue= wait= service= status=503 bytes=

Any idea how to draw more information out of heroku logs - or find out what is wrong?
I had a similar problem, every time I hit the server, I just got these 2 useless lines of output in the logs.
When I ran:
heroku restart
It ended up showing me more output that let me track down my issue (related to migrating to cedar) (the app was crashing on deploy it appears, never fully starting up, but not showing an error during the deploying process, as would usually occur).
According to their Developer documentation:
Check your app’s backtrace in the logs to find out what you need to do to fix the problem.
https://devcenter.heroku.com/articles/errors
I had similar issues and it was related to the dynos. H10 error.
Just run:
heroku restart
Fixed it for me!
Had a similar problem and the error was masked, running a rails c on heroku gave us the reason for the crash
