How to find agent identifier together with alert name using Alerts Polling

[Anon Anon]

Hi, Everyone,

I am facing a dilemma when I am trying to use Alerts polling web service to list the alerts that have crossed danger threshold together with agent identifiers.

What I do is making a call to web service getAllAlertsSnapshot to find out the module name and alert name that is in danger state (numeric is 3) ,

Based on the module name and alert name I suppose to use another web service to find the related agent identifier such that I can quickly locate the agent that is having problem.

Unfortunately, API Reference Guide for CA Application Performance Management does not give such a web service. The most close web service is getAlertSnapshot but it requires agent Identifier as input.

Do we have a solution for my problem , or I am using it wrongly?

Thanks for listening.

Cyril

Hi Cyril,

One of the developers gave me the following answer for you:

You need to call the AgentService operation getAllAgents.

Then he can compare the FQDN and Host name to find the appropriate agent. The connector code looks like this

String host = alert.getAgentHost().toLowerCase();
for (DAgentSnapshot snapshot : agents)
{
String snapshotHostName = snapshot.getHostName();
String snapshotFQDN = snapshot.getFqdn();
if (((snapshotFQDN != null) && snapshotFQDN.toLowerCase().equals(hostLC))
|| ((snapshotHostName != null) && snapshotHostName.toLowerCase().equals(hostLC)))
{
logger.warn("processLegacyAlert agent found fqdnName " + host);
createAlertCIHelper(snapshot, process, agent, propsMap, host, nonDuplicates);
break;
}
logger.warn("processLegacyAlert matching agent for legacy alert " + host + " not found");
}


Please let me know if that solves your problem.

Regards,

Florian.

Hi Florian.

Thank your for the reply.

Just a few questions. how do you create or where do you get object "[color=#280aeb]alert[color]" in the below line in your codes ?
String host = [color=#280aeb]alert[color].getAgentHost().toLowerCase();

I am using web service [color=#280aeb]getAllAlertsSnapshot[color] but it does not seem to return [color=#280aeb]FQDN[color] , host information , or [color=#280aeb]agent identifier[color] that I can use to match an appropriate agent.

Below are the information returned by [color=#280aeb]getAllAlertsSnapshot[color] (described in http://<host>:<port>/introscope-web-services/services/AlertPollingService?wsdl )

■ alertCurrStatus type int
■ alertName - nullable; type string
■ alertPrevStatus type int
■ alertStatusChanged type boolean
■ manModuleName - nullable; type string
■ simpleAlert type boolean
■ thresholdValue type int

Hi Cryil,

Here's the response from our Engineer:

"I am using


http://<host>:<port>/apm-web-services/services/AlertService?wsdl

getStateOfLegacyAlerts();

For updates we use SNMP traps – not the web service

If you want to use the old web services, some rough pseudo code:

managedModules=getManagedModules
for each managedModule in managedModules
agentSnapshots= getAgentSnapShots(managedModule .managedModuleName)
for each agentSnapshot in agentSnapshots
alerts= getAlertSnapshots(managedModule .managedModuleName ,agentSnapshot.agentIdentifier)
// you now have a list of alerts for agentName+ managedModuleName
"

Keep us posted,

Florian.

Hi Florian,

Thanks for following up my question.

I tried http://<host>:<port>/[color=#2e07f3]apm-web-services[color]/services/AlertService?wsdl but it gives me HTTP 404 (page not found error), however, http://<host>:<port>/[color=#2e07f3]introscope-web-services[color]/services/ works.

I am using introscope 9.1.1. Is there any specific configuration I need to do?

I followed the instruction in docment "CA Application Perfomance Management API Reference Guide" to edit <INTROSCOPE_HOME>/config/IntroscopeEnterpriseManager.properties and add below line to enable web serivce:

introscope.alerts.extension.managementmodules.enable

However, it only works on web services in http://<host>:<port>/[color=#2e07f3]introscope-web-services[color] , but not http://<host>:<port>/[color=#2e07f3]apm-web-services[color]/services which has HTTP 404 error

You have a typo: it's AlertsService?wsdl not AlertService?wsdl

Thanks for the reply and pointing out the error.

Yes, I am able to get http://../apm-web-services/../AlertsService?wsdl  from one environment ( we have multiple introscope environements for development, testing and load testing). But on another enviornment, I am still getting HTTP 404 error while http://../introscope-web-services/.. works. Is there any log I can look at to check what is causing that?

I tried getStateOfLegacyAlerts defined in AlertsService?wsdl on the environment where there is no HTTP 404 error for wsdl retrieval, it gives empty result but  I am sure there should be multiple alerts in introscope. The empty result is like below: 

  <?xml version="1.0" encoding="UTF-8" ?>

- <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

- <soapenv:Body>

- <ns1:getStateOfLegacyAlertsResponse soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:ns1="com.wily.apm.model.webservices">

  <getStateOfLegacyAlertsReturn soapenc:arrayType="ns2:DAlertSnapshot[0]" xsi:type="soapenc:Array" xmlns:ns2="urn:com.wily.apm.model.webservices.common" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" />

  </ns1:getStateOfLegacyAlertsResponse>

  </soapenv:Body>

  </soapenv:Envelope>

 

What could have gone wrong?

Thanks heap

Cyril
