event_filter by IP?

[William Rehnquyst <rehnquyst () gmail com>]

Hi,

We have an alert that is generated quite often on one specific host only,
and there's isn't anything we can do on the host to remediate this as it is
a necessary service. It's something we want to keep an eye on but not be
overwhelmed by.

Since this is a known issue, we can limit the alert on this host, but we
don't want to simultaneously limit this alert on other hosts as it can stop
us from discovering new issues.

Is there any way I can do the equivalent of event_filter by a specific IP?
As far as I know event_filter applies to all IPs and I can't specify IP. We
don't want to completely suppress it. As far as I know pass rule has no
rate limit.

Maybe there's some way to rewrite the rule that I don't know of? So far the
only example of rewriting a rule I've seen is declaring a variable and then
!$ the var, which again acts as a pass rule.

Any ideas? Or is my only recourse suppression?

Appreciated,
Rehn
