Default node monitor is not configured-f5-all
Vendor: f5
OS: all
Description:
It is good practice to have a basic check for node monitors as it’s easier to fast establish correlations between multiple failing members during an outage. Indeni will alert when a device that supports node monitoring does not have it configured.
Remediation Steps:
Log in to the web interface. Click on “Local Traffic” -> “Nodes” -> “Default Monitor” and then assign a default monitor.
|This particular monitor should determine status on a node level and thus ICMP is recommended.
|
|Make sure to do this during a scheduled service window as a failed node monitor brings down all members that the node is associated to.
How does this work?
This alert uses the iControl REST interface to extract the default node monitors.
Why is this important?
It is good practice to have a basic check for node monitors as it’s easier to fast establish correlations between multiple failing members during an outage.
Without Indeni how would you find this?
Login to the device’s web interface and click on “Local Traffic” -> “Nodes” -> “Default Monitor”. This would show the default monitor configuration for nodes.
