Alerting configuration

[emanuel]

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?

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:~ #

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.
