Maintenance windows affects SLA?

[alextovar72]

Hi:

Several metrics have been configured for SLA measurement. The schedule is the "default" schedule.

Is there a way to stop the SLAs (or suspend the tests) when a window maintenance takes place? This is in order to not affect the SLA compilance.

Thanks all for your help

Alex.

Hi Alex,

If there is a known period of time when maintenance tasks are performed, you can create a custom schedule and use it for the SLA measurement. For example, if you know that services may be unavailable between 2:00am and 4:00am on Sat nights, you can create a new schedule under Administration -> Other -> Custom Schedules -> Create A Schedule. Provide a suitable name like "Exclude Sat Maint" and deselect the "2" and "3" checkboxes for "Sat" and Click on "Create Schedule".

Now navigate to Administration -> SLA and click on "Update" for the SLA measurement inquestion. Finally, Select "Exclude Sat Maint" for the schdule and apply the changes. This will instruct Traverse to ignore any outage/events during those two hours when calculating the SLA.

As a side note, during unschedule maintenance you can suspend the devices and/or tests used for the SLA measurements and resume them after the services have been restored. Since the tests will not be executed during that time, the SLA measurement will not be affected either.

Hey Rajib:

Thanks for your answer, so suspendig the tests will avoid affecting the SLA results, is there a way to suspend many tests? e.g., 200 tests at the same time?

Thanks !

Hi Alex,

The BVE API server is perfectly suited for this type of bulk operation. For example, to suspend all ping/Packet Loss tests across all devices, you can use a command like this:


test.suspend "deviceName=*", "testName=Packet Loss", "testType=ping"


Or use a command line following to suspend all tests on specific set of devices:


test.suspend "deviceName=*router*", "testName=*"


Likewise, "test.resume" command can be used to resume normal monitoring once the maintenance is complete. Description of this and other BVE API commands are available in the Developer's Guide under the Documentation section of our Support Portal (http://zyrion.com/support/users/)
