NAME

       hobbit-alerts.cfg - Configuration for for hobbitd_alert module

SYNOPSIS

       ~xymon/server/etc/hobbit-alerts.cfg

DESCRIPTION

       The hobbit-alerts.cfg file controls the sending of alerts by Xymon when
       monitoring detects a failure.

FILE FORMAT

       The configuration file consists of rules, that may  have  one  or  more
       recipients associated. A recipient specification may include additional
       rules that limit the circumstances when this recipient is eligible  for
       receiving an alert.

       Blank  lines  and  lines  starting  with a hash mark (#) are treated as
       comments and ignored.  Long  lines  can  be  broken  up  by  putting  a
       backslash  at  the end of the line and continuing the entry on the next
       line.

RULES

       A rule consists of one of more filters using these keywords:

       PAGE=targetstring Rule matching an alert by the name of the page in BB.
       This  is  the path of the page as defined in the bb-hosts file. E.g. if
       you have this setup:

              page servers All Servers
              subpage web Webservers
              10.0.0.1 www1.foo.com
              subpage db Database servers
              10.0.0.2 db1.foo.com

       Then  the  "All  servers"  page  is  found   with   PAGE=servers,   the
       "Webservers"  page  is PAGE=servers/web and the "Database servers" page
       is PAGE=servers/db. Note that you can also use regular  expressions  to
       specify  the  page  name,  e.g.  PAGE=%.*/db  would  find the "Database
       servers"  page  regardless  of  where  this  page  was  placed  in  the
       hierarchy.

       The  PAGE name of top-level page is an empty string. To match this, use
       PAGE=%^$ to match the empty string.

       EXPAGE=targetstring Rule excluding an alert if the pagename matches.

       HOST=targetstring Rule matching an alert by the hostname.

       EXHOST=targetstring Rule excluding an alert by matching the hostname.

       SERVICE=targetstring Rule matching an alert by the service name.

       EXSERVICE=targetstring Rule excluding an alert by matching the  service
       name.

       GROUP=groupname  Rule  matching  an alert by the group name. Groupnames
       are assigned  to  a  status  via  the  GROUP  setting  in  the  hobbit-
       clients.cfg file.

       EXGROUP=groupname Rule excluding an alert by the group name. Groupnames
       are assigned  to  a  status  via  the  GROUP  setting  in  the  hobbit-
       clients.cfg file.

       COLOR=color[,color]  Rule  matching  an  alert  by color. Can be "red",
       "yellow", or "purple". The forms "!red", "!yellow"  and  "!purple"  can
       also be used to NOT send an alert if the color is the specified one.

       TIME=timespecification  Rule matching an alert by the time-of-day. This
       is specified as the DOWNTIME timespecification in the bb-hosts file.

       DURATION>time, DURATION<time Rule matcing an alert  if  the  event  has
       lasted longer/shorter than the given duration. E.g. DURATION>1h (lasted
       longer than 1 hour) or DURATION<30 (only  sends  alerts  the  first  30
       minutes). The duration is specified as a number, optionally followed by
       ’m’ (minutes, default), ’h’ (hours) or ’d’ (days).

       RECOVERED Rule matches if the alert has recovered from an alert  state.

       NOTICE  Rule matches if the message is a "notify" message. This type of
       message is sent when a host or test is disabled or enabled.

       The  "targetstring"  is  either  a   simple   pagename,   hostname   or
       servicename, OR a ’%’ followed by a Perl-compatible regular expression.
       E.g. "HOST=%www(.*)" will match any hostname that  begins  with  "www".
       The same for the "groupname" setting.

RECIPIENTS

       The  recipients  are  listed  after  the  initial  rule.  The following
       keywords can be used to define recipients:

       MAIL address[,address] Recipient who receives  an  e-mail  alert.  This
       takes one parameter, the e-mail address.

       SCRIPT  /path/to/script  recipientID  Recipient  that invokes a script.
       This takes two parameters: The script filename, and the recipient  that
       gets passed to the script.

       IGNORE  This  is  used  to define a recipient that does NOT trigger any
       alerts, and also terminates the  search  for  more  recipients.  It  is
       useful  if  you have a rule that handles most alerts, but there is just
       that one particular server where you dont want  cpu  alerts  on  Monday
       morning.   Note  that  the  IGNORE  recipient  always has the STOP flag
       defined, so when the IGNORE recipient is matched,  no  more  recipients
       will  be  considered.  So the location of this recipient in your set of
       recipients is important.

       FORMAT=formatstring Format of the text message with the alert.  Default
       is  "TEXT"  (suitable  for e-mail alerts). "PLAIN" is the same as text,
       but without the URL link to  the  status  webpage.  "SMS"  is  a  short
       message  with  no  subject  for SMS alerts. "SCRIPT" is a brief message
       template for scripts.

       REPEAT=time How often an alert gets repeated. As with DURATION, time is
       a number optionally followed by ’m’, ’h’ or ’d’.

       UNMATCHED  The  alert  is  sent  to  this  recipient  ONLY  if no other
       recipients received an alert for this event.

       STOP Stop looking for more recipients after this one matches.  This  is
       implicit on IGNORE recipients.

       Rules  You  can  specify  rules  for  a recipient also. This limits the
       alerts sent to this particular recipient.

MACROS

       It is possible to use macros in the configuration  file.  To  define  a
       macro:

            $MYMACRO=text extending to end of line

       After  the  definition  of a macro, it can be used throughout the file.
       Wherever the text $MYMACRO appears, it will  be  substituted  with  the
       text of the macro before any processing of rules and recipients.

       It  is  possible to nest macros, as long as the macro is defined before
       it is used.

ALERT SCRIPTS

       Alerts can go out via custom scripts, by using the SCRIPT keyword for a
       recipient.   Such  scritps  have  access  to  the following environment
       variables:

       BBALPHAMSG The full text of the status log triggering the alert

       ACKCODE The "cookie" that can be used to acknowledge the alert

       RCPT The recipientID from the SCRIPT entry

       BBHOSTNAME The name of the host that the alert is about

       MACHIP The IP-address of the host that has a problem

       BBSVCNAME The name of the service that the alert is about

       BBSVCNUM  The  numeric  code  for  the  service.  From   the   SVCCODES
       definition.

       BBHOSTSVC HOSTNAME.SERVICE that the alert is about.

       BBHOSTSVCCOMMAS  As  BBHOSTSVC,  but dots in the hostname replaced with
       commas

       BBNUMERIC A 22-digit number made by BBSVCNUM, MACHIP and ACKCODE.

       RECOVERED Is "1" if the service has recovered.

       EVENTSTART Timestamp when the current status (color) began.

       SECS Number of seconds the service has been down.

       DOWNSECSMSG When recovered, holds the text "Event duration : N" where N
       is the DOWNSECS value.

       CFID  Line-number  in the hobbit-alerts.cfg file that caused the script
       to be invoked.  Can be useful when troubleshooting alert  configuration
       rules.
