Customizing Alert Severities and Selective Alert Sending
- Kiss, Mate
AVAILABLE IN VERSION 9.6.4 AND LATER
Verba alert priorities can be overridden by a provided severity. The alerts can be also turned off for specific alert targets or turned off entirely. For this, a rule XML file has to be created on the server(s).
Creating an Alert Rule XML
Step 1 - Create the alert_rules.xml file under the [APPLICATION_FOLDER]\settings\ folder, then open it for editing.
Step 2 - Paste in the following template for the XML file:
<?xml version="1.0" encoding="UTF-8"?> <alert_rules> <rule oid_filter="oid_regexp" severity="" disabled_targets=""/> </alert_rules>
Step 3 - Configure the rules the following way:
| Property | Description |
|---|---|
| oid_filter | A regex filter that has to match the last three numbers of the alert OID. For example: "\.115\.0\.1" matches to the alert OID 1.3.6.1.4.1.39067.115.0.1 "\.115\.0\.." or "\.115\.0\.\d" matches to alert OIDs 1.3.6.1.4.1.39067.115.0.1-9 "\.115\.0\.\d{2}" matches to alert OIDs 1.3.6.1.4.1.39067.115.0.10-99 |
| severity | Sets the new severity for the alert(s). If not specified, the default severity of the alert(s) will be used. Possible values:
|
disabled_targets | Specifies to which alert targets should not the alert be sent. If not specified, the alert(s) will be sent to all targets. Possible values:
Multiple values can be provided, separated by a comma. |
Examples:
<rule oid_filter="\.115\.0\.1" severity="0"/> - Diables the alert 1.3.6.1.4.1.39067.115.0.1.
<rule oid_filter="\.115\.0\.1" severity="5"/> - Sets the severity to NOTIFICATION level for the alert 1.3.6.1.4.1.39067.115.0.1.
<rule oid_filter="\.115\.0\.1" disabled_targets="all"/> - Diables the alert 1.3.6.1.4.1.39067.115.0.1.
<rule oid_filter="\.115\.0\.1" disabled_targets="mail"/> - The alert 1.3.6.1.4.1.39067.115.0.1 will be sent to all targets, except to email.
<rule oid_filter="\.115\.0\.1" disabled_targets="mail,snmp"/> - The alert 1.3.6.1.4.1.39067.115.0.1 will be sent to all targets, except to email and SNMP.
<rule oid_filter="\.115\.0\.1" severity="5" disabled_targets="mail"/> - Sets the severity to NOTIFICATION level for the alert 1.3.6.1.4.1.39067.115.0.1, and it will not be sent to email.
Step 4 - Save the file, then restart the Verba System Monitor service.
Step 5 - Repeat the steps on each server where you want to change the default alert sending.
