The alert correlation training file is a CSV (comma-separated values) file that provides input data for machine learning to understand alert patterns and drive alert correlation.
The data is saved in a table structured format. The training file is generally a text file containing information separated by commas to determine the alert patterns.
Downloading a sample training file
The sample, downloadable training file contains sample metric names. Alerts triggered in a sequence (as provided in the training file) are correlated.
To download a sample training file:
- From All Clients, select the client.
- Go to Setup > Alerts > Alert Correlation.
- From the ALERT CORRELATION POLICIES page, click +.
- From the Policy Definition section, click Download an example file.
The sample training file should now be downloaded.
Creating a training file
A training file can be created or modified from the sample training file.
To create a training file:
- Open a new spreadsheet.
- Enter the metric names.
Alerts triggered in a sequence as provided in the training file are correlated.
- Save the training file as CSV UTF-8 (Comma delimited).
The order of the sequence is important. Therefore, provide all the necessary sequences in a proper order for accurate results.
Using a wild card
A wild card character asterisk (
*) is used when the exact metric name is unknown or when there are a large nummber of metric sequences and permutations. A wild card card acts as a placeholder that represents any value or an empty character string.
For example, an IT administrator wants to correlate the following alerts:
vmware.vcenter.alarm.HostEsxCosSwapAlarm, vmware.vcenter.alarm.HostLicenseEditionNotAllowed, vmware.vcenter.alarm.HostMemoryUsageAlarm, vmware.vcenter.alarm.HostVendorProviderRegistrationAlarm
Listing all these metric sequences and all its permutations might be a tedious task. Therefore, the IT administrator lists one partial sequence with asterisks like
vmware.vcenter.alarm.* in the training file.
