Troubleshooting
Problem
After deploying the IBM Cloud Pak for AIOps to Netcool/Impact connector, the Netcool/Impact server stops sending data to DASH widgets.
Symptom
Dashboard widgets connected to a Netcool/Impact data set no longer show any data and report a ATKRST132E or 404 error message instead.
Cause
During the integration of the connector, a set of AIOPs policies and parameter files are imported into Netcool/Impact.
The UI data provider for Impact is unable to process the new parameter files, which blocks the processing of all data sets.
Diagnosing The Problem
Dashboard widgets connected to a Netcool/Impact data set report an ATKRST132E or 404 error message in the DASH system log:
ATKRST132E An error occurred while transferring a request to the following remote provider: 'Impact_NCICLUSTER.example.com'. Error Message is '404:Cannot access data provider - Impact_NCICLUSTER.example.com'.

The following errors are reported in the Impact GUI server's message.log:

An examination of the parameter files for the AIOPS_HandleAction and AIOPS_ExecJS policies shows the following values:
cat /opt/IBM/tivoli/impact/etc/NCI_AIOPS_HandleAction.params
impact.params.1.name=inputData
impact.params.1.format=String
impact.params.2.name=inputMetadata
impact.params.2.format=String
impact.params.numparams=2
impact.dtparams.1.DTNAME=policyOutputData
impact.dtparams.1.DTTYPE=String
impact.dtparams.1.POLICYVARIABLENAME=AIOpsPolicyOutput
impact.dtparams.numparams=1
cat /opt/IBM/tivoli/impact/etc/NCI_AIOPS_ExecJS.params
impact.params.1.format=String
impact.params.1.name=AIOPS_JS
impact.params.numparams=1
Resolving The Problem
Upgrade to fix pack 7.1.0.33
The problem was resolved by APAR IJ49120. Upgrade to Netcool/Impact fix pack 7.1.0.33 to apply the APAR fix.
Alternative solution
To resolve the issue in earlier fix packs, use the following procedure to replace the parameter files for the AIOPS_HandleAction.js and AIOPS_ExecJS.js policies.
1. Open an SSH terminal to the backend Impact server.
2. Stop the Impact servers:
/opt/IBM/tivoli/impact/bin/stopGUIServer.sh
/opt/IBM/tivoli/impact/bin/stopImpactServer.sh
3. Navigate to the policy directory:
cd /opt/IBM/tivoli/impact/policy
cd /opt/IBM/tivoli/impact/policy
4. Create a backup of the parameter files:
cp <SERVER>_AIOPS_HandleAction.params <SERVER>_AIOPS_HandleAction.params.bak
cp <SERVER>_AIOPS_ExecJS.params <SERVER>_AIOPS_ExecJS.params.bak
where <SERVER> is the name of the Impact server. For example:
cp NCI_AIOPS_HandleAction.params NCI_AIOPS_HandleAction.params.bak
cp NCI_AIOPS_ExecJS.params NCI_AIOPS_ExecJS.params.bak
5. Replace the content of the <SERVER>_AIOPS_HandleAction.params file with the following text:
impact.params.1.name=inputData
impact.params.1.format=String
impact.params.1.value=
impact.params.1.label=inputData
impact.params.1.desc=
impact.params.2.name=inputMetadata
impact.params.2.format=String
impact.params.2.value=
impact.params.2.label=inputMetadata
impact.params.2.desc=
impact.params.numparams=2
impact.dtparams.1.DTNAME=policyOutputData
impact.dtparams.1.DTTYPE=String
impact.dtparams.1.value=
impact.dtparams.1.POLICYVARIABLENAME=AIOpsPolicyOutput
impact.dtparams.1.IMPACT_DATATYPE_NAME=
impact.dtparams.1.IMPACT_DATASOURCE_NAME=
impact.dtparams.numparams=1
impact.eicparam.enabled=false
impact.tasksparam.numparams=0
impact.uidataproviderparam.enabled=false
6. Save the file.
7. Replace the contents of the <SERVER>_AIOPS_ExecJS.params file with the following text:
impact.params.1.format=String
impact.params.1.name=AIOPS_JS
impact.params.1.value=
impact.params.1.label=
impact.params.1.desc=
impact.params.numparams=1
8. Save the file.
9. Restart the Netcool/Impact servers:
/opt/IBM/tivoli/impact/bin/startGUIServer.sh
/opt/IBM/tivoli/impact/bin/startImpactServer.sh
