HowTo get 3par disk IO stats into Zenoss

Mar 292010

I’ve come to realize, that CIM is the new SNMP, but on steroids. Most new SAN, NAS, Network, and Operating Systems now support CIM/WBEM. To me it is easier to gather statistics and information through CIM, then it is through SNMP. In this article I am going to give you a script that will allow you to query the 3par for Disk IO stats. You will be able to grab Disk IO stats on a per Volume, per Port, or per Disk basis.You will also be able to search for a Volume, Port, or Disk, instead of just dumping all the Volumes, Ports, or Disk.

Before you download this script, you will need to download pywbem from sourceforge and install it. .

get3ParIOstats.py == Download

All the data that you get from the script, must be saved as a COUNTER and not a GAUGE.

Here is an example of searching for statistics by DISK for DISK 2:6:1..

python get3parIOstats.py -u "http://3par" -a 'login passwd' -s '2:6:1' --diskOK|2:6:1_ReadIOs=67236384 2:6:1_WriteIOs=28457131 2:6:1_TotalIOs=95693515

How to find Alerting Rules using the Zenoss API

Mar 192010

Good Afternoon my fellow Zenoss users. here I bring you another Python tool to use with Zenoss. This tool will allow you to list all of your alerting rules, either by Group, User, or Query. If you are like me and have over 100 Alerting Rules. Managing these rules are more then a pain in the butt. Especially when you create a new rule and you know you created it correctly, but it just does not work… Well you might have another conflicting rule. Well what do you do in this situation?? You can go through each rule manually and sooner or later you will find it.

Or you can use my tool to find it for you. You might ask… How will yout tool find the conflicting rule for me??? Well to be honest it will not find the rule for you. What it can do is search all the rules for a certain query. Which can return one or more alerting rules if they are similiar in nature. or you can have the tool, list all of your Alerting rules. Or you can have the script list all of your alerting rules by group or user. The toll will report back to you The Group/User, The Alerting Rules attached to that Group/user, and the Schedules Attached to that Alerting Rules.

Where this tool really helped me, was when the DST changed happened. None of my schedules were working anymore, so the work around is to move all the schedules ahead of time. Using this script I found all my schedules very quickly, with out haveing to go through each of my alerting rules one by one.

HowTo add Multiple DataPoints to Zenoss using the Zenoss API

Mar 052010

I’ve seen a few people in the Zenoss community forums asking for an easier way to add multiple Datapoints into Zenoss, instead of adding 1 by 1. Well, I’ve decided to try and build such a tool today. Now even though the tool is not complete (IN MY EYES). It is already has been helpful to me! As of right now the script can List Templates in a Organizer ( aka /Devices/Server/Linux ) or in a Device ( zenoss1.linuxdynasty ).

It can also create a Template, with a Command DataSource, with Multiple DataPoints. This means you can now automate the creation of Templates and DataSources and DataPoints. So if you are using a tool like Puppet, Cfengine, Bcfg2, or Chef, this process can be automated. I will be adding more features in the next few weeks.

Any question or help about this script, please post them here http://www.linuxdynasty.org/forums/Scripting/scripting/ZenossTemplateManager
UPDATES!!!!!!

Update 1.0.6, Fixed an issue where if youdo not pass the -G option for graph it will fail.
Update 1.0.5, Now have the ability to add multiple graphs with multiple datapoints
Update 1.0.4, Now have the ability to create thresholds, bind templates to class or device, set severities on thresholds and
datasources, attach datapoints to thresholds.
Update 1.0.3, I broke down the templateManager function into 3 smaller functions. You also can now list templates and datasources for either device or organizer, and list datapoints for a device. I also added more verbosity with the -V option.
Update 1.0.2, You now do not have to pass a command with the script. So i f you already have a command in the DataSource, it wll not get overwritten.. Thank you Eangel, for telling me about this issue..

Upcoming Features such as….

Deleteing Templates, DataSources, and DataPoints
Copying Templates
Adding Graphs

The tool is called Zenoss_Template_Manager.py. You can download it here..
