How to monitor Apache?
Hi. There are several options with Apache
a) Web Server Agent: when installing an Apache Web Server Agent - see details Apache Web Server Agent Configuration - then you will automatically get Process Health Data for the Web Server as explained here: Web Server Monitoring
b) If you do not have a Web Server Agent you can always use the Apache Monitor Plugin: Apache Monitor Plugin
Hi Andreas,
Thanks for your reply, actually for above question our goal is try to grab http response header.
Currently we have a requirement to capture information from http response header using dynatrace 5.5.
For example, we want to get “Content-Type” field from http Response Headers. Do Dynatrace have this feature to capture response header?
I have attempt to configure Transaction base measure<Web Request –Response Header> .
But seem like that it didn’t work, we cannot get the field of header. So can you please help check if I have done the configuration correctly?
Or if you have any other approach to capture http response header, kindly suggest us. Thanks
Attached detail snapshot.
You are on the right track - there is only one thing missing:
The Measure you created will "extract" this piece of information from the PurePath and make it available for the Business Transaction. Now - what you need to make sure first is that this piece of context information is actually captured ON the PurePath. Capturing Context Information is done through our Sensors, e.g: Web Server, Servlet, ASP.NET, ... In your case you want to configure the Web Server Sensor which allows you to capture both Request and Response Headers. Go to your System Profile - click on the Agent Group where you have the Web Server Agent placed, click on Sensor Configuration and then on Properties for the Web Server Sensor Pack. There you can define which headers you want to capture. Once this is turned on your PurePaths will contain that additional context information and then you can use the Measure to extract this data and use it for your BT

Thanks for your help,I have below questions:
- For option a) Apache Web Server Agent Configuration, I have add the following line to your Apache configuration file (httpd.conf)
LoadModule dtagent_module "<agentPath>" |
but here we cannot add an arguments on this line(See below samples for Tomcat configuration). So when I come to add a new agent group for Apache in dynatrace <agent mapping > page, I don't know what to fill in Alias and Agent Name for this apache agent. Do we have a way to specify an argument here?
Sample: agent group for Tomcat.
===================
Tomcat\config.properties:
enableDebug=false
extraJavaArgs=\ -agentpath\:"D\:\\ptc\\x-12-M070.12\\ Tomcat \\dtLib\\64\\dtagent.dll"\=name\=ptc.wt.Tomcat,server\=localhost\:9999 <For Apache , we don’t know how to add this arguments >
javaVM=server
jpdaAddress=tomcat
…..
Sanpshot for apache agent config:
2. How to validate this piece of context information is actually captured on the PurePath? Do we have a way to check this?
Hi,
the Apache agent is configured through the dtwsagent.ini file located in <dynaTrace installation directory>/agent/conf - that's where you can change the agent name as well as the collector to connect to (please see Web Server Agent Configuration for a full description)
If you capture a header field you should be able to see the captured data when you right-click on the web request node in the purepath and choose Details
Hope that helps
Hi, previous responses and links were for Apache HTTP Server. It seems you want to place an agent on Apache Tomcat, in that case the doc is here: Apache Tomcat
Sorry, I misread the previous post.
Hi Dynatrace support,
I have done the configuration as per Apache Web Server Agent Configuration,
Currently in the agent group view, I can see a web server agent for Apache, but I still don’t get what I expect. We cannot get the header info from http response. Besides, When I shutdown the apache webserver, I still can see the web agent in the agent group view.
Can u pls help check my configuration?
if I config as below I will encounter:too many 'Web Server' agents connected;license exhausted;
LoadModule dtagent_module "C:\Program Files\dynaTrace\dynaTrace 5.5.0\agent\lib\dtagent.dll"
Hi,
Do you currently have a license for Apache agents? You can check in the server settings page, tab license - called web server agents.
The message above indicates that you either have not bought web server agents or have more connected than you licensed.
Best, Roman
I'm also trying to monitor the Apache webserver with dynaTrace, but when doing this the Apache server is hanging.
I've added this in the http.conf.
LoadModule dtagent_module /appT/apachet1/dynatrace-5.5.0/agent/lib64/libdtagent.so
I can't see any serious problems in the logs. Only "2014-01-22 13:35:24.778643 [256/00000001] warning [native] Web server agent did not start up after 10 seconds. Continuing execution."
After starting the Apache webserver, the server doesn't respond at all. Has someone an idea what's going wrong?
