How to monitor agents & Listeners without using SMA & AES?

We are running through an issue where agents are down frequently and every time we have to login to SMA to start. We would like to implement automated solution which can monitor agents in all nodes and can send a notification if agent is down or got exception. I saw in forums we can achieve it by using AES, but we don't want to use it for now. Any help will be much appreciated. We are using PRPC 6.1SP2, OS-AIX and installed on WAS 7x Thankyou.

Hi ,


You can  try setting the Log Levels to “debug” for the agents themselves by enabling below classes for debug.:


com.pega.pegarules.engine.context.Agent
com.pega.pegarules.engine.context.BatchRequestorTask
com.pega.pegarules.engine.context.agent


So, whenever there will be an error related to any agent it will be showing the exception in the logs.


You can also check below link if it helps:

Thanks,

Hi,


If it is an production we won't recommend to enable debug level on classes, it leads to performance issue and log files size should grow.


Whenever Agent down in pega alert log there is an PEGA0010 alert , you can write custom logic to trigger the mail based on this alert.

Hi Siva,


The following ways you can monitor agents outside of SMA and AES is


 


a- monitor agent status from an external application that use appropriate remote JMX protocol for your platform to call PRPC, execute the agent status mbean and interpret the XML results.


The command-line jmxterm will work as an example.


 


b- monitor agent status from an external application that calls a PRPC SOAP or HTTP service. In the public API there is an agentUtils object can provide you with access to current agent status. See step 1 of activity pzCheckSearchAgentStatus (below)


 


c- monitor agent status from an external application that calls a PRPC SOAP or HTTP service that uses the pega API method to call the agentStatus mbean methods. In the AESRemote ruleset there is an executeMbean service and activity. In the PegaAES ruleset there are activities to make a SOAP request to a node to call mbean com.pega.pegarules.management.AgentManagement operation AgentStatusAdvanced (then apply a parse-xml to interpet the results).


 


code sample for agentStatus


 com.pega.pegarules.pub.context.AgentUtils agentUtils = tools.getAgentUtils();


 com.pega.pegarules.pub.util.StringMap systemPulse = agentUtils.getQueue("Pega-RULES", 1);


 com.pega.pegarules.pub.util.StringMap systemIndexer = agentUtils.getQueue("Pega-RULES", 2);


 com.pega.pegarules.pub.util.StringMap systemWorkIndexer = agentUtils.getQueue("Pega-RULES", 5);


 agentError = systemPulse == null || !Boolean.valueOf(systemPulse.getString("IsEnabled")).booleanValue() || !"".equals(systemPulse.getString("LastExceptionData"));


 agentError = agentError || systemIndexer == null || !Boolean.valueOf(systemIndexer.getString("IsEnabled")).booleanValue() || !"".equals(systemIndexer.getString("LastExceptionData"));


 agentError = agentError || systemWorkIndexer == null || !Boolean.valueOf(systemWorkIndexer.getString("IsEnabled")).booleanValue() || !"".equals(systemWorkIndexer.getString("LastExceptionData"));

Hi Sudhakar,


Thanks a lot for the inputs.


Basically I'm from production support  and having limited knowledge on these coding things. Can you please guide me on where & how I need to setup the above code.


 


Any help will be much appreciated.

Hi,


You can check the step 1 of the pzCheckSearchAgentStatus for sample code.
