An Example of Creating a new SLA:
---------------------------------
by Christian Zimmerman
Problem: We need to create a new SLA because the default SLA's aren't going to meet our needs.
We want to monitor disk space on the server and be notified when : disk space used is > 99% of the total disk space.
Things we need to do:
1. Create a new Event Type
2. Create a new SLA Conditions Individual Definition
3. Create a new SLA group
4. Associate the newly created condition with the new SLA Group
5. Create a new Trigger (allows for notification if needed)
6. Add a rule for the trigger
Step One:
=========
Goto Administration > Internal Configuration > Event Analyzer > Event Types
You should see a list of all event types. Click the ADD link to create a new Event.
Now we need to input a description, severity, and event text. Enter the following:
Description -> Disk Full-SLA
Severity -> select Critical
Event Text -> Disk <interface>: <info>
Next put a check in the next two boxes: Show in Event Viewer? and Event Generates an Alarm?
Once this is completed click the submit button and now you should see this new event in the list with all the other events.
Step Two:
=========
Goto Administration > Internal Configuration > SLA definitions > SLA Conditions Individual Definition
Again we will need to add the condition that we will want to test for so lets create a new condition.
Click the ADD link to begin creating a new condition.
You will need to fill in the following fields Description, Show Info, Condition, Show Expression, and Show Unit.
Here are the values:
Description -> Used Storage > 99%
Show Info -> Used > 99%
Condition -> ( <storage_used_blocks> > ((<storage_block_count>*99)/100))
Show Expression -> ((<storage_used_blocks> * 100)/<storage_block_count>)
Show Unit -> %
Once you've entered the information in, click submit and your new condition is created.
Steps Three and Four:
=====================
Goto Administration > Internal Configuration > SLA definitions > SLA Conditions Groups
Here we will need to create a new SLA group. Click the ADD button and lets create a new group.
Here is a list of fields that we need to fill in: Description, Interface Type, Event Type,
Alarm State, Event Text, Threshold % (for Reports). Here's the values:
Description -> Storage Full
Interface Type -> Storage
Event Type -> Disk Full-SLA
Alarm State -> Alert
Event Text -> Storage
Threshold % -> 100
Notice the value for the Event type is the one we created.
This is where we link the Event Type to the SLA.
When the SLA is met or not met depending on how you setup the triggers, an event will be generated.
Click submit and your new SLA group is created.
You should see your new event group now with a view link right next to it.
This view link is where we associate the condition to check for, if the condition is met an event is generated.
So click the view button and a second frame opens up right below the SLA groups.
Click the ADD link and a new box appears. Under the "Condition" option select -> Used Storage > 99% and then click the SHOW option.
Click submit. We have now created a new SLA option on which will test whether or
not our Server disk space usage is above 99% ( meaning its full or almost full).
If the SLA is met then an event type will be generated.
Step Five:
==========
Goto Administration > Internal Configuration >Triggers & Filters > Triggers Configuration
Now that our SLA is setup we need to setup a trigger for notification.
(Note: You don't have to setup a trigger, but you might as well as you can turn them off later if needed without any hassle.)
Click the ADD link and fill in the Description and Type fields:
Description -> Disk Full
Type -> Match Events
Click submit and your done.
Step Six:
=========
The trigger has been created, but we haven't told the trigger what action to perform to lets do this now.
Click on View Rules for the Trigger "Disk Full". A Triggers Rules Administration window shows below the Triggers.
Click the ADD link. We need to edit these options: Field, Operator, Value, Action, Action Parameters.
Set them to this:
Field -> Type
Operator-> IN
Value -> Disk Full-SLA
Action -> Send Mail
Action Parameters
subject -> Disk <interface-interface>
comment -> <alarm-type_description> <interface-description>
Click submit and your done. This trigger will now send an email to the email configured in your profile when the SLA has been met.
You should also see an event as well.
