This directory should contain executable programs to handle CTDB event
|
||
|
notifications. The first and only argument passed to each program is
|
||
|
the event, which is one of:
|
||
|
|
||
|
init, setup, startup, unhealthy, healthy
|
||
|
|
||
|
To use notifications with this directory then you need to set:
|
||
|
|
||
|
CTDB_NOTIFY_SCRIPT=/etc/ctdb/notify.sh
|
||
|
|
||
|
in your CTDB configuration file.
|
||
|
|
||
|
An example script that sends SNMP traps for unhealthy/healthy might
|
||
|
look like this:
|
||
|
|
||
|
#!/bin/sh
|
||
|
|
||
|
case "$1" in
|
||
|
unhealthy)
|
||
|
# Send an SNMP trap saying that the node is unhealthy:
|
||
|
snmptrap -m ALL -v 1 -c public 10.1.1.105 ctdb \
|
||
|
$(hostname) 0 0 $(date +"%s") ctdb.nodeHealth.0 i 1
|
||
|
;;
|
||
|
healthy)
|
||
|
# Send an SNMP trap saying that the node is healthy again:
|
||
|
snmptrap -m ALL -v 1 -c public 10.1.1.105 ctdb \
|
||
|
$(hostname) 0 0 $(date +"%s") ctdb.nodeHealth.0 i 0
|
||
|
;;
|
||
|
esac
|
||
|
|
||
|
Alternatively, email could be sent:
|
||
|
|
||
|
#!/bin/sh
|
||
|
|
||
|
case "$1" in
|
||
|
unhealthy)
|
||
|
mail -s "$(hostname) is UNHEALTHY" foo@example.com </dev/null >/dev/null 2>&1
|
||
|
;;
|
||
|
healthy)
|
||
|
mail -s "$(hostname) is HEALTHY" foo@example.com </dev/null >/dev/null 2>&1
|
||
|
;;
|
||
|
esac
|
||
|
|
||
|
When adding programs please note the exclusion patterns in notify.sh.
