Alert suggestion: RSS

[Ginther, Demian M]

Posted earlier.

I have noticed one issue with these RSS notifications... RSS is designed
to work on half hour updates, and most RSS clients won't allow you to
update much more often than 25 minutes.

Anyway, it's till nice to have a ticker tape of nagios alerts.

Can you post your solution with the perl XML::RSS script solution?

This is pretty much the same as mine except I used perl and a perl
module called XML::RSS to do the work.

I'll post it after I eat lunch.

Quoting "Ginther, Demian M" <demian.m.ginther at boeing.com>:

looks like 3 of us have been hacking and came up with 3 different kind
of solutions! viva tmtowtdi!

my hack:

miscommands.cfg

define command{
    command_name    notify-by-rss
    command_line /usr/local/nagios/libexec/notify-by-rss.sh
"$NOTIFICATIONTYPE$"
"$SERVICEDESC$" "$HOSTALIAS$" "$HOSTADDRESS$" "$SERVICESTATE$"
"$DATETIME$" "$OUTPUT$"
    }

the script:

#!/bin/sh

RSSFILE="/var/www/html/rss.xml"
DESC="alerts for
NAGURL="http://whatever"

NOTIFICATIONTYPE=$1
SERVICEDESC=$2
HOSTALIAS=$3
HOSTADDRESS=$4
SERVICESTATE=$5
DATETIME=$6
OUTPUT=$7-
echo "<?xml version='1.0' encoding='utf-8' ?>" >$RSSFILE
echo "<rss version='2.0'>" >>$RSSFILE
echo "<channel>" >>$RSSFILE
echo "<title>nagios alert</title>" >>$RSSFILE
echo "<link>$NAGURL</link>" >>$RSSFILE
echo "<description>$DESC</description>" >>$RSSFILE
echo "<lastBuildDate>$DATETIME</lastBuildDate>" >>$RSSFILE
echo "<generator>nagios notify script</generator>" >>$RSSFILE echo
"<item>" >>$RSSFILE echo "<guid isPermaLink='true'>$NAGURL</guid>"
>>$RSSFILE echo "<pubDate>$DATETIME</pubDate>" >>$RSSFILE echo
"<title>$NOTIFICATIONTYPE alert on $HOSTALIAS for service
$SERVICEDESC</title>" >>$RSSFILE echo "<description>" >>$RSSFILE echo -e
"\nNotification Type: $NOTIFICATIONTYPE\nService:
$SERVICEDESC\nHost:
$HOSTALIAS\nAddress: $HOSTADDRESS\nState: $SERVICESTATE\nDate/Time:
$DATETIME\nAdditional Info:\n$OUTPUT" >>$RSSFILE echo "</description>"
>>$RSSFILE echo "</item>" >>$RSSFILE echo "</channel></rss>" >>$RSSFILE
exit 0

Obviously it'll only report the latest alert, not the best solution. Had
to niggle with group ownerships (added nagios to apache group, chmod g+w
the write
directory)

blah someone write a complete clean solution :)
