Pool member / server response time high-f5-all
Vendor: f5
OS: all
Description:
indeni will alert if the ping from the load balancer to specific servers is too high.
Remediation Steps:
Review any networking or communication issues which may cause this.
How does this work?
This alert logs into the F5 through SSH and extract all node IPs and gathers statistics by pinging each node.
Why is this important?
Nodes having slow response times may be indicative of an application health issue. It is important to measure the response time of each node against a calculated average to note if it’s too high.
Without Indeni how would you find this?
Log into the device through SSH. Enter TMSH and issue the command “cd /;list ltm node recursive”. Ping each node and note as to whether the response time is above expected threshold.
