hobbit-alerts.cfg - Configuration for for hobbitd_alert module
The hobbit-alerts.cfg file controls the sending of alerts by Xymon when
monitoring detects a failure.
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
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
subpage db Database servers
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
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
GROUP=groupname Rule matching an alert by the group name. Groupnames
are assigned to a status via the GROUP setting in the hobbit-
EXGROUP=groupname Rule excluding an alert by the group name. Groupnames
are assigned to a status via the GROUP setting in the hobbit-
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.
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.
It is possible to use macros in the configuration file. To define a
$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.
Alerts can go out via custom scripts, by using the SCRIPT keyword for a
recipient. Such scritps have access to the following environment
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
BBHOSTSVC HOSTNAME.SERVICE that the alert is about.
BBHOSTSVCCOMMAS As BBHOSTSVC, but dots in the hostname replaced with
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
hobbitd_alert(8), hobbitd(8), xymon(7), the "Configuring Xymon Alerts"
guide in the Online documentation.
