[hobbit] hobbit-alerts.cfg regex/MACRO problem - need help

Thu Nov 16 10:06:23 CET 2006

Total guess here but maybe you could try changing:

HOST=%(prod-.*) SERVICE=* EXHOST=$UNUSED_PROD
     MAIL $PRIMARY color=red REPEAT=60 RECOVERED NOTICE format=sms
     MAIL $SECONDARY color=red DURATION>20 REPEAT=60 RECOVERED NOTICE
format=sms

To:

HOST=%(prod-.*) EXHOST=%$UNUSED_PROD
     MAIL $PRIMARY color=red REPEAT=60 RECOVERED NOTICE format=sms
     MAIL $SECONDARY color=red DURATION>20 REPEAT=60 RECOVERED NOTICE
format=sms

And obv remove the % from the start of $UNUSED_PROD, just "my 2 cents
worth"

Thanks,
Jason.

I'm still having this problem. If anyone has any ideas I'm open to
suggestions :)

I am trying to use a regex macro to exclude a number of hosts from an
alert.  Here is the one I was using at first:

$UNUSED_PROD=%prod-app-(2|3|4|5|6|7|8|9|10|11|12|18|20|21|22|23|24)|prod
-web-(1|2|3|4|9|10|11)

Here is how I am using it for the actual alert definition:

HOST=%(prod-.*) SERVICE=* EXHOST=$UNUSED_PROD
     MAIL $PRIMARY color=red REPEAT=60 RECOVERED NOTICE format=sms
     MAIL $SECONDARY color=red DURATION>20 REPEAT=60 RECOVERED NOTICE
format=sms

I ran into a problem with the host "prod-app-12" matching the regex. I
realized this was because I was not terminating the numbers, so I
changed my variable to:

$UNUSED_PROD=%prod-app-(2|3|4|5|6|7|8|9|10|11|12|18|20|21|22|23|24)$|pro
d-web-(1|2|3|4|9|10|11)$

This SHOULD work according to online regex testing tools, and I also at
Henriks advice, verified it using "pcretest":

$ pcretest
PCRE version 6.6 06-Feb-2006

  re>
/prod-app-(2|3|4|5|6|7|8|9|10|11|12|18|20|21|22|23|24)$|prod-web-(1|2|3|
4|9|10|11)$/
data> prod-web-12
No match
data> prod-web-11
 0: prod-web-11
 1: <unset>
 2: 11
data>

As seen above, the host "prod-web-12" does NOT match, but "prod-web-11"
DOES, which is exactly how I want it. 

However, when I use this in hobbit-alerts.cfg. I do not get the expected
behavior. Instead, ALL hosts match, according to pages sent out and from
viewing the "info" section.  The strange thing is, according to
hobbitd_alert --test, the hostname was successfully excluded, but
clicking on the "info" column for hosts that are supposed to be excluded
reveals that they are still configured to alert.

../bin/hobbitd_alert --test prod-web-11 procs --color-red
00009993 2006-11-09 21:48:30 send_alert prod-web-11:procs state Paging

0<1200)
...
00009993 2006-11-09 21:48:30 Failed 'HOST=* SERVICE=*
EXHOST=$UNUSED_PROD' (hostname excluded)

* Another thing, when I do the same test as above, using hostname
"prod-web-12", which is a host that should NOT be excluded,
hobbitd_alert still says that it was excluded (same last line of output
as the prod-web-11 test above).

I have also tried enclosing the regex in quotes, which didn't work
either.

If anyone has any insight, please let me know. I have contacted Henrik
about this, but I believe he misread my email, as he suggested that I
add $ to the regex, which I had already tried...so now I am hoping that
he or someone else sees this message and can see what Im doing wrong.
