Re: [Keepalived-devel] Query keepalived for information such as current priority?

[Quentin A. <qu...@ar...>]

Paul,
SNMP is probably the way to go. For state, it would be possible to
track that via notify_scripts or notify_fifos, but you can't get
priority that way. There is also the option to parse JSON output, but
that isn't ideal at the moment, and there is also DBus, but I can't
remember what is available via that. Finally it would be possible to
send SIGUSR1 to the parent keepalived process and parse the
/tmp/keepalived.data file, but that really isn't recommended.
You state that "some of the information is not available". Which MIB
are you using? The RFC based VRRP and VRRPv3 MIBs don't provide as much
information as the proprietary KEEPALVIED MIB. If there are specifics
that you need that are missing from SNMP, then they could be added to
the KEEPALIVED MIB. Can you provide a list of the specific information
that you would like to be available.
