Linux Installation Package instead of .jar file

Hi Anton,
there are tared shell scripts for Apache and PHP Agents (see e.g. Apache Web Server Agent Configuration#AgentInjectionCopy/PasteExamplesLinux/UNIX), because there might be no Java on the machine where these items are installed.

For all Agent jar installers an ancient Java 1.4 is sufficient. This should be available?!

For the one or two dynaTrace Servers Java 1.6 should hopefully not be a problem?!

How about the Collectors? Are the boxes without Java 1.6 or later? Is that the problem?
You could extract the private Java 1.7 form the dynaTrace installer jar and use this for installation!

Please mind that we already got a considerable number of installers (we tried to be thoughtful!) for different OSes and bitnesses, full and / or Server-, Collector- and Client-only, half a dozen Agents or so, ADKs,... Adding variants complicates documentation and might confuse people more than it helps.

What component do you have specifically in mind?
Thanks
G.

Hi Guenter

I understand the complications you are describing. Mostly it is only for Agents.  The Server and Collectors we do manually.  We are rolling the Host Agent out to about 1000 Linux servers, so a Package will make automatic roll-out of any of the agents easier.

Thanks

Anton

Hi Anton,
I can´t verify this now as I´m on the commute, but to try a solution NOW:

I think you can easily roll your own by extracting the Host Agent from the jar and run a shell script to deploy it to the hosts and chkconfig add the daemon to boot.
Sounds reasonable?
G.

Cool.  I'll try it.

Hi again,
hope this already works for you?

#extract dthostagent and libdtagentcore.so from agent/lib64/ in the jar
#extract init.d/dynaTraceHostagent from the jar

#mimic Agent directory structure on the host
mkdir dynatrace-agent-5.6.0
mkdir dynatrace-agent-5.6.0/agent
mkdir dynatrace-agent-5.6.0/agent/lib64
mkdir dynatrace-agent-5.6.0/agent/conf

#copy dthostagent and libdtagentcore.so to agent/lib64/
#write a basic dthostagent.ini (see below) to agent/conf
#copy dynaTraceHostagent shell script to /etc/init.d
#be sure the Name specified in dthostagent.ini is mapped in some tier
#try the Agent before you add it to boot
#/etc/init.d/dynaTraceHostagent start
chkconfig add dynaTraceHostagent

dthostagent.ini

Name host
Server CollectorToConnectTo

Hopefully the hosts have some talking Name so you can distinguish them by the Agent name.

Did you make sure that the Host Agent has permissions to write to its own directory – so that the bootstrapper can download new versions from the Collector?

One other important thing / quote from the documentation:
Only use the Host Agent to monitor a machine where no other Agent runs, because if there is any other Agent running it can / will take over the Host Agent role.

I think I will add this bulk installation thing to the regular documentation as I heard of several customers with this and larger sizes.

Thanks for asking! Have fun!
G.

Great, thanks for the feedback!

The install seem to work fine with the automatic installation tool as described by Guenter.

Our model at the moment is that even if a Java/Webserver agent is installed, we install a Host Agent pointing to a different dynaTrace Server/Collector anyway.  If the Java app crashes, we still have visibility of the machine/OS.  This seem to work well.

Thanks again.

Anton

I just integrated this in the documentation.

Glad you asked.
G.

Hi Guenter,

We are trying to install the Dynatrace Host Agents on the Linux servers. We have installed the Host Agent on the Database Server, started the dthostagent service, made updates in the .ini file after creating the Tier in the System Profile. Still it is not getting detected in the Dynatrace client. Very Frustrating, as we have restarted the services multiple time and no response. Do you have any link which could help or a generalized installation document, that you would mind sharing. I will appreciate any help provided.

Thanks
