One of our Network Engineers needed some monitoring (internal temp, external temp, and external humidity) added for an AVTech Room Alert 4E unit, preferably using a check_MK plugin. Couldn’t find one in any repos or in git, so decided to add this to a growing collection of plugins I’ve been working on. Another request from the same team: MinuteMan UPS units. I’ll be adding to my check_mk_bag git repo periodically with any new, custom check plugins.
As of Cisco CDA Patch 2, identity mappings provided via Cisco ISE are natively supported. This means you can authenticate against ISE, which may in turn authenticate against LDAP or Active Directory, and subsequently notify one or more Cisco CDA servers that a new user-to-IP mapping exists. Cisco accomplishes this exchange of authenticated identities via syslog messages. ISE is configured to forward syslog messages to the CDA server(s), and the CDA server(s) have the sending ISE server(s) configured as a syslog “client.
Thought I’d share a nice wrapper for netsh and dnscmd calls to allow easy, bulk provisioning of new DHCP scopes. It’s nice being able to provision a ton of these at once by piping the output from Import-CSV! ############################ #AUTHOR: JR Morgan #CREATED: 20120417 #MODIFIED: 20140611 ############################ <# .Synopsis Adds DHCP Scope to ALL specified DHCP servers. If split-scope is desired the script uses IP Math to automatically add the desired exlcude ranges.

My wife is tiny… 5 ft tiny… Suffice it to say I needed a safe and easy way to load (and unload) my motorcycle without assistance. I researched the expensive solutions from LoadAll and deemed it unnecessarily complicated (with far too many moving parts) for my taste. I also didn’t want to sacrifice my truck cargo space. I decided on the 40″ wide, 8 ft. long Black Widow Ramp from DiscountRamps.
Inventoried replicated folders and their corresponding backlog counts Before you even get started, make sure your Powershell execution policy is set to RemoteSigned for your standard AND x86 Powershell console; Check_MK will generally execute PS scripts from the x86 console, so it’s critical to set the policy for both: Start > Accessories > Windows PowerShell Right-click ‘Windows PowerShell (x86)’, select ‘Run As Administrator’ Execute: Set-Execution Policy RemoteSigned Repeat the same steps above, but for the standard ‘Windows PowerShell’ console.
If you need more output than what the existing Check of MySQL Status Variables includes, such as Seconds_Behind_Master or Relay_Log_Pos, consider adding a quick line to the bash call for _mysqlstatus on the agent. This assumes you’ve installed themysql_status-1.0.1.mkp and deployed the necessary agent files to the servers you’d like to monitor. This also assumes you’ve correctly configured the credentials needed to run the plugin and successfully receive (standard) output from the agent plugin.
If you have redundant Windows 2008 DHCP servers (likely with split-scope configurations), you’re familiar with the problem of keeping reservations between the servers synchronized. I figured I’d post a script I created to sync reservations between servers. Synchronization can be 1-to-1 or 1-to-many, depending on your redundant DHCP server configuration. This script can sync with ALL authorized DHCP servers in a domain if needed. Make sure to read the included Powershell help information.
Someone important suggested this get posted somewhere so that anyone else experiencing check_http socket timeout problems with client/servers running Microsoft System Center 2012 Endpoint Protection would have a clue as to what could be causing issues: If you’re receiving strange/unexpected timeouts from the check_http plug-in when running it against a server using Microsoft System Center 2012 Endpoint Protection, the Network Inspection Service may be blocking your check attempt. Don’t bother trying to force an agent string or any other weird options; either switch to header-checks-only [no body] using the -N option with check_http, or disable your Network Inspection service entirely (not recommended).
