-> From command prompt, execute below command to generate cluster.log in C:\Windows\Cluster\Reports.

Cluster log /g

-> From command prompt, execute below command to generate a verbose cluster.log in location C:\Windows\Cluster\Reports.

Cluster log /g /Level:5

-> Cluster.log generated from command prompt will be using Coordinated Universal Time (UTC) and not local time. 

-> From powershell, execute below command to generate cluster.log of all nodes to one destination directory with local time stamp.

Get-ClusterLog -UseLocalTime -Destination .

-> We cannot specify level of details in Cluster.log if generated from powershell.

-> Sometimes, level of details while generating cluster.log can be important during troubleshooting. Always On Availability group can be a good example. This can be solved by changing “VerboseLogging” property of Availability Group resource in Cluster Administrator from default value 0 to 2. The resource should be made offline and online or wait till next failover to have this take effect and then generate the cluster log again.
