Diagnostics - Metric for downtime of ProbeOpen in a New Window

Is there a metric I can refer to in order to know the total amount of time that the probe/Application Server JVM was down on a WebLogic Server?

I know of the Probe Availability metric which gives this value in terms of percentage but it becomes harder for me to answer the question that the probe was unreachable for x number of minutes/hours using this metric.

I was also hoping to use this metric to reliably report when a probe becomes unreachable and comes back up but that is secondary for now.

HP Diagnostics Java Agent and Probes on WebSphereOpen in a New Window

Hi-

I have a Host Server A, where I have App1, App2 App3 installed based on a webserver Websphere 8.5. I installed the Java agent on the Host Server A. Then I did the instrumentation from same path /opt/MercuryDiagnostics/JavaAgent/DiagnosticsAgent/bin using ./jreinstrumenter.sh -i /usr/ws/java/jre.


I used the generated path in the JVM Parameter in WebSphere as described in the guide.
-Xbootclasspath/p:/opt/MercuryDiagnostics/JavaAgent/DiagnosticsAgent/classes/IBM/1.6.0/instr.jre -javaagent:/opt/MercuryDiagnostics/JavaAgent/DiagnosticsAgent/lib/probeagent.jar -Xshareclasses:none

How do I identify each probe on Diagnostics server since all the apps are on the same Host server. And in case I need to skip one of the app how may I manage to skip it out from the JVM Parameter?

Thank you,

 

 

Problem while installing HP Diagnostics ServerOpen in a New Window

Hi all, 

I am trying to install HP Diagnostics Server. I've followed the installation step and finished the installatioin. But the server doesn't seem to run. I couldn't visit the 'localhost:2006' as said in the guide. When I look at 'netstat -aon' in the command line, the server listens on port 23472, but I still couldn't visit 'localhost:23472'. And I can't open the 'Administration' in 'HP Diagnostics Server' in the start menu, neither. Could someone help me to solve this problem, please? Thanks in advance.

Diagnostics .GET( ) .POST( )Open in a New Window

Good afternoon.

 

We started using Diagnostics some days ago. Now that there is more data collected, we noticed that the calls with the biggest latency are a .GET( ) method and a .POST ( ). Even if we drill down on these calls there seems to be no specific information of this methods. Could this be because we have not installed an agent on the side of the DB?

 

Thank you!

Help with using the API calls from diagnosticsOpen in a New Window

Hi

I am able to build my Query up and if I am logged into diagnostics and I open a new tab and run the query it works and comes back with the desired results

however the moment I close Diagnostics connections in my browser and try posting the query again it fails ,

this I understand will happen as there is nowhere in the query that allows fro user name and password to be forwared to the diagnostic server

http://Commander.Company .corp:2006/query/?granularity=%5Bname%3D%275m%27%5D&action=summary&response_format=html&path=%2Fgroupby%5Bname%3D%27Default+Client%27%5D%2Findex%5Bequals%28name%2C%27apps%27%29%5D%2Fapp%5Bequals%28uid%2C%27CP2oyg6jS2a_EtWX9zmKOA%27%29%5D%2Fapp_metrics.

i have hunted high and low for a document that expains how to embed a user name and password call into the request.

The BSM API has this documented  and we use this quite a bit ,but low and behold the same mecahanisum does not seem to work on Diagnostics

Just before you ask why I would want to do this , it makes it easier to give a group of people a dash board to look at with figures in it  rather than trying to teach them what all the wiggles and squigles mean .

I have allready tried using user.Password @ server .company ,com method , IE throws out a security warning
