ESX disk monitoring with SIM

[Superfly.nn]

Hi all,

I would like to monitor all storage (local and SAN) attached to my VMware ESX(3.5 U1) hosts using HP SIM (Build version: C.05.01.00.02). I have configured the snmpd.conf and tested with some traps. So far so good. I have set disk threshold on 95% for critical and 85% for major. I have setup an Automated Event handling email alert so the admin team get threshold breaches alerts. However the emails are never sent. I have loaded a datastore to 96% and nothing.
How can I get this working and how can I check the frequency the agent polls the server for alerts.

Thanks,
Niall.

Track the chain:

You say the email doesn't get sent, but is there in fact an event that HP SIM has received?

Did a trap get generated? There should be an entry on the ESX host in /var/log/messages corresponding to cciss and one corresponding to cmaidad if it's for local storage.

What is the 'datastore' that you loaded up? Do you see the size at 96% on the System Management Homepage?

Default frequency is 1 minute. See http://www.hp.com/go/proliantlinux --> More Linux Documentation --> "Managing ProLiant Servers with Linux" for information on setting the polling interval. (The ESX agents are based on the Linux agents)

niall,

the agents on the esx server should send traps back to hp sim when they occur, the auto event handler then picks them up and actions whatever.
are you getting an event appearing in sim for the threshold breach and if so have you checked the last run time on your auto task, if it has run when or after the event appeared in sim then check your e-mail settings.
assume snmp strings are configured ok in smh on esx and in sim.


hope this helps

We don't appear to have an event for HP SIM to respond to.

I have checked the logs and I see no snmp entry coresponding to the disk threshold as you have highlighted in /var/log/messages with cciss.

The datastore is a normal LUN that is presented as datastore_7. I have had to remove some data from that datastore which is now at 76% capacity. So I have moved the thresholds to 60% for major and 70% for critical on that LUN only, using the SMH webpage.

So if the ESX host is not creating the log for the event then it is likely to be a problem with the Agent or snmp config???

I've attached a graphic of the LUN and the thresholds.

Thanks for the help.

niall,

in smh settings is the data source set to snmp ? if not set that and use the test indication to send a trap back to sim.

Hi Mark,

The ESX servers have recently been rebooted and we received email notification from the specific auto event handler that I setup (All major and critical events to be emailed to my teams email distro list) so the email is ok and snmp strings config seems ok. But the specific disk threshold breaches are not be getting emailed to us.

Forgot to mention that the LUN (datastore_7) we are using for this test is FC SAN based.

To give an overall idea of what we are achieving:
We have a disk monitor script from the below URL which emails the team an overall disk report first thing every morning:
http://www.yellow-bricks.com/2008/01/21/checking-the-diskspace-on-your-vmfs-volumes/#

But we need to be highlighted of disk capacity changes during business hours by email alerts.

niall,

that's not necessarily true, ping from the default availability task would have
brought up a system unavailable event.

Mark,

I've opened smh -> Settings but I don't have an option to change the source. I assume it is snmp already as we have an snmpd.conf configured. The snmp config is attached. Maybe you can see something an incorrect configuration.

Your help is appreciated and points are being applied.

niall,

the data source defaults to wbem as far as i know.

Mark,

I have no option to change the datasource in the settings page of SMH for the server in question.
I never seen an option to change the datasource for ESX host agents and never read about this in the doco from HP.
Attached is a pic of what I do see.
Do I have to edit a config file to change default data source to snmp. Are you refering to a feature in Windows based agents?
