Check_MK check for Fortigate firewalls

I've got a Fortigate 60C and wanted to monitor it in Check_MK. I could find a plugin written by Justin McMillen, but it didn't work in the version 1.1.2 of Check_MK. Also they seemed to use SNMP OIDs, which my Fortigate 60C didn't have. So I've updated his checks and created a new version of the plugin. The checks use SNMP to get CPU and RAM usage as ell as the session count. You can download the package from Check_MK Exchange site.

Version 1.3.2 of Ex2010_MBDB_Info released

Again I've released a new version of the check. I've changed only the Windows plugin. Now the spaces in a mailbox database name are replaced by underscores. I hope this change would help all of you, who experienced problems with the plugin.

To update it's enough to download the new check package, install it in your check_mk instance by a command like this:

cmk -vP install Ex2010_MBDB_Info-1.3.2.mkp

and substitute the cmd file on your Exchange server by the Ex2010_MBDB_Info.ps1 file from the new package.

You can find the new version of the package at the known place at the check_mk plugin exchange site.

Version 1.3.1 of Ex2010_MBDB_Info released

I've released a new version of the check. I've changed the Windows plugin. It is now a pure Powershell script, not a command script anymore. It should run smoothly to avoid problems, which some of you had in the past running the plugin.
To update it's enough to download the new check package, install it in your check_mk instance by a command like this:

cmk -vP install Ex2010_MBDB_Info-1.3.1.mkp

and substitute the cmd file on your Exchange server by the Ex2010_MBDB_Info.ps1 file from the new package.

Upgrade Microsoft Hyper-V Linux IC from 3.3 to 3.4

Recently I had to upgrade the integration components on a lot of CentOS virtual systems running on a Hyper-V failover cluster. During the upgrade procedure I faced a couple of things, which I'd like you to be aware of. The version on the guest VM is CentOS 6.3, the Hyper-V failover cluster is running under Windows Server 2008 R2 SP1 and consists of 6 nodes.

Below is the output of LVM related commands before starting the upgrade of Linux IC:

Find differences in Public Folder replicas

This is a small piece of code to run it in EMS and to help you finding differences in item number in a public folder structure. The powershell script shows the number of elements in each sub folder for the both of Exchange 2010 servers, which public folder replicas are located on. Below is an example output of the script.

Check_MK check to show some data about Ex2010 mailbox databases

A few days ago I finished to test a new check for check_mk and published it as package at Check_MK Exchange. I named the check "Ex2010_MBDB_Info". In this article I'd like to share a couple of details about the check and its functionality.

The purpose of the check is to get the size of mailbox databases and the count of the mailboxes in each of them. The check package consists of the check itself, the plugin for check_mk agent, the perf-o-meter helper file and the pnp-template.

Extending a LVM partition in a Hyper-V guest VM running CentOS

Imagine a scenario like the following: you have a Hyper-V host and a CentOS 6.3 guest. The CentOS guest has Microsoft Integration Services for Linux 3.3 installed and running. A data file system on the guest is running out of the free space:

[root@myhost ~]# df -h /data/svn/

Filesystem            Size  Used Avail Use% Mounted on

/dev/mapper/data-svn   99G   93G  964M  99% /data/svn

Although the partition is a part of LVM, but your entire disk is almost full. In the article I'd like to show how you can get rid of this without getting your services offline.
