Re: Query keepalived for information such as current priority?

Paul,

You can dump the state of Keepalived in human-readable format using "kill -s USR1 $(cat /var/run/keepalived.pid)".
This will create a file in /tmp/keepalived.data

For stats, you can use signal USR2 instead. It will create a file in /tmp/keepalived.stats.

Finally, if you want both in json format, you need to compile Keepalived with --enable-json (there is a dependency towards libjson-c when compiling),
you can then use signal 36 (kill -s 36) to create the /tmp/keepalived.json

You can find tools that use these functions here https://github.com/acassen/keepalived/tree/master/tools/json_tracking

Regards,
