Alerting configuration

Hello all again ...

Through operations manager / performance advisor, can you setup tier thresholds?

... say if we are watching snapshot usage on a system, can we setup alerts at 20%, 50%, 75%, etc as various degrees of alerts?  And if we can set up tiered alerts, can we classify them with different severity levels?

Re: Alerting configuration

yes.

Below is an example for volume full.

lnx186-149:~ # dfm eventtype list -C "df.kbytes"
Event Name                                         Severity     Class
-------------------------------------------------- ------------ ------------------
volume-almost-full                            Warning      df.kbytes
volume-full                                   Error        df.kbytes
volume-space-normal                           Normal       df.kbytes
lnx186-149:~ #

The events uses the following thresholds values which are set using the below options.

lnx186-149:~ # dfm options list | grep -i volFullThreshold
volFullThreshold                      90
volFullThresholdInterval              0 seconds
lnx186-149:~ # dfm options list | grep -i volNearlyFullThreshold
volNearlyFullThreshold                80
lnx186-149:~ #

you can also modify the severity of an event if you wish.

using the  cli as shown below.

lnx186-149:~ # dfm eventType list volume-almost-full
Event Name                                         Severity     Class
-------------------------------------------------- ------------ ------------------
volume-almost-full                            Warning      df.kbytes
lnx186-149:~ # dfm eventType modify -v Normal volume-almost-full
Modified event "volume-almost-full".
lnx186-149:~ # dfm eventType list volume-almost-full
Event Name                                         Severity     Class
-------------------------------------------------- ------------ ------------------
volume-almost-full                            Normal       df.kbytes
lnx186-149:~ #

Re: Alerting configuration

Hi,

Operations Manager provides fixed set of thresholds (usually normal, nearly-full and full). Operations Manager does not allow additional threshold levels to be configured. For example, you cannot add a new threshold level between nearly-full and full.

Thanks,

Raj.
