EventSentry SysAdmin Tools: New SNMP query utility “snmptool”

I’m excited to announce a new version of our free EventSentry SysAdmin Tools which, in addition to bug fixes and minor improvements, also includes a new command-line tool: snmptool. This brings the total number of utilities in the toolkit to thirty (30)!

Free SNMP tools for Windows® are not easy to find and often require you to memorize the various OIDs in order to test a remote host’s SNMP functionality, or to get useful information back.

Our free snmptool utility solves that problem by giving you a simple utility which downloads a variety of stats, depending on what the remote host provides via SNMP, and displays it to the user. For example, if you are querying a VMWare® ESXi™ host with the snmptool, it will – among other stats – enumerate all VMs configure on the host, whereas it will display switch port mappings when querying a switch.

The snmptool currently retrieves the following:

  • System Description string
  • Operating System
  • Uptime
  • Current CPU usage
  • Network interfaces (name, MAC address, IP if available)
  • Mounted disks
  • Running processes
  • Virtual Machines (ESXi™ only)
  • Switch port mappings

Running the utility is incredibly easy, simply specify the SNMP credentials and the remote host, and the utility will do the rest on its own:

C:\>snmptool /u public linuxserver

The output is completely dynamic, if no processes are found (e.g. you are querying a switch) then that section will simply be omitted.

In addition to the brand new snmptool, version of the EventSentry SysAdmin Tools includes the following other improvements:

Added the new /a parameter which checks the target folder against a pattern for additional safety

Added support for authenticating against a login page, including login pages which redirect

I hope the new utility and other improvements will help make your job easier. Oh, and you can download the EventSentry SysAdmin Tools here.
