Welcome to Dell Technologies VxRail - How to Series.
How to collect vSAN observer logs.
Reference Dell Knowledge Article # 503827.
This video was created to show how to collect vSAN observer logs
to review performance of the current system.
This video presents how to connect to RVC (Ruby vSphere Console).
How to start the performance gathering collection.
How to gather these files.
This procedure can be used to review statistics
about VxRail cluster performance
and before opening a service request with VxRail support
regarding performance issues.
Before you begin
you should have gathered root credentials of vCenter
and SSO admin password.
As a first step we need to log to the vCenter appliance
using root credentials.
Then log on RVC console using SSO admin account.
We navigate to local host.
And then to VxRail data center
then choosing "computers"
and finally the vSAN cluster.
LS can be used to list the cluster names.
Once on the correct cluster, we can use the vSAN observer command
to launch the tool and start the performance data collection.
Collection is not starting.
We can now wait for the time we want to monitor
and use CTRL + C to stop the data collection.
Once stopped
path of the stored bundle is reported on the last output line.
We can now connect to the vCenter
using for example, WinSCP and gather the file.
These are the main parameters.
--interval sets how long the observer waits
between gathering information in seconds.
In the example, it is gathered every 30 seconds.
--max-runtime sets the total duration the vSan observer will run.
In the example, it will run for one hour total.
If max-runtime is not set, it will default to two hours.
--generate-html-bundle builds a tar.gz bundle with HTML files.
If you wish to leave monitor, and not gather logs for later review
you can leave generate-html-bundle
out of the command.
Thank you for watching.
