Troubleshooting Issues with Generating JMBs
Problem:
Description: No JMB is generated on a device running Junos OS.
Solution
AI-Scripts generate JMBs when an event occurs on the
device on which they are installed and store the JMBs in the /var/tmp directory of the device. Service Now then
copies the JMBs and the attachments from the device to /var/cache/jboss/SN/Jmb/output of the Junos Space
Appliance. The JMBs and attachments are deleted from the device after
they are copied to the Junos Space Appliance. From the Junos Space
Appliance, the JMBs along with the attachments are uploaded to Juniper
Support System (JSS) when the incident is submitted to JSS for creating
a case.
To troubleshoot issues with JMB generation:
- Log in to the device.
- Enter CLI mode and execute the show log default-log-messages
| match AIS_DATA_AVAILABLE command.
An output similar to the following is displayed if the JMBs are generated.
