And how do you monitor the announced ip-addresses?

Question

Monitoring

Colleagues, good afternoon.
There was a need to monitor announced vip-addresses from wheelbarrows.
What a task:
suppose there are 5 fronts of a high-load project. they are hung with a vip-address, which is registered in the dns.
it is necessary to monitor how many wheelbarrows this vip announces at the moment.
Are there any schemes how this can be done (and is it possible) at the server level, without getting into NOC equipment? Thank you.

Answer 1

You make a self-made check for the zabbix agent, for example, on bash: we
check the output of the "ip a" command for the presence of your vip address and then return 0 or 1
