Monitoring

Hi

I wonder if anyone could help.

The person who dealt with the HP San as now left the company and nobody knows anything about it.

At the moment its running but I dont want it to run out of disk space or anything else.

Could anyone advise how to monitor on a daily basic or better still automate something when its near critical.

In the meantime I'm hoping to find a course to go on.

Many thanks

Re: Monitoring

For basic alerting there is built in thresholds and SMTP based email notification that you can configure using the Centralized Management Console (CMC)

I have been developing some methods for building more robust monitoring solution using open source Nagios to provide alerting, notification, as well as historical graphing for utilization, performance and other health monitors.

If you would like some assistance getting a health check and making sure you are getting proper notification and monitoring please feel free to call us. We provide these services, and would be happy to help you configure this on your SAN cluster.

Re: Monitoring

These are an initial draft, but I think they could be helpful in building a monitoring solution for you.

I'd appreciate any feedback on these documents.

Thanks!

Re: Monitoring

Thanks for your help.

Im just trying to get my head around the left hand use summary.

In the non provisioned summary I have 1tb of free space. Does this mean when the provisioned volumes run out it borrows from the non provisioned?

Hope it makes sense.

Thanks

Re: Monitoring

Not Provisioned is simply capacity that does not yet have volume or snapshot data on it.

One thing to remember, is thin provisioned volumes will consume from the "Not provisioned" as you add data to them.

"Provisionable Space" is how much space you would consume if all your thin provisioned volumes used every last MB allocated to them.

Since the LeftHand SAN doesn't have an eye into the underlying filesystems, it is important that when using thin provisioning you monitor your usage, and also its a good idea to monitor the freespace inside the operating system of the systems using thin provisioned volumes.. That way you can have multiple "early warning" systems if you begin to approach over-utilization that you specify in alerts.
