Check Windows Network Traffic/Usage

Write a Review

Description:

This plugin uses check_nt, which is part of the official Nagios plugin collection. However with check_nt you only get to check one value (e.g. Bytes sent/s). If one wants to create graphics with Bytes_in and Bytes_out, there is need to bundle two checks in one. This is where this plugin plays its part. It launches two check_nt checks (one for Bytes sent/s and one for Bytes received/s) and bundles both checks to one common output.

Language-Problems
by ViktorEngelmann, December 31, 2019

On my german machine, it didn't work although I used the flag "-l de" (to set the language to german). The problem was that (in addition to use "Netzwerkadapter" instead of "Network Interface") it also needs to query for "Empfangene Bytes/s" instead of "Bytes Received/sec" and "Bytes gesendet/s" instead of "Bytes Sent/sec"


Windows server 2012 & 2016
by scudieroa, April 30, 2019

For my Server 2016 I had to manually go to "Administrative Tools" > Performance Monitor > Data Collector Sets > User Defined > Server Manager Performance > Performance Counters...If you select "Add" under "Network Interface" you can see the exact names of the interfaces you can monitor. On my 2016 server this name was slightly different from the description name on the adapter. Once I mirrored the name from here, all worked! I also added the "-c" & "-w" options to the .sh for setting the critical and warrning levels, works great!

Hey - this plugin works great on Windows 2012 but I keep getting the following error on 2016: ./check_win_net_usage.sh -H 10.3.0.14 -p 12489 -i Broadcom NetXtreme Gigabit Ethernet _2 Network UNKNOWN: NSClient - ERROR: No performance data from command: check_pdh Thoughts? Thanks in advance.

MS changed the counters on W2012. To get it to work on 2012 change these lines bytes_in=$(${pluginlocation}/check_nt -H ${host} -p ${insertport} -s ${password} -v COUNTER -l "Network Interface(${interface})Bytes Received/sec") bytes_out=$(${pluginlocation}/check_nt -H ${host} -p ${insertport} -s ${password} -v COUNTER -l "Network Interface(${interface})Bytes Sent/sec") else # Without password bytes_in=$(${pluginlocation}/check_nt -H ${host} -p ${insertport} -v COUNTER -l "Network Interface(${interface})Bytes Received/sec") bytes_out=$(${pluginlocation}/check_nt -H ${host} -p ${insertport} -v COUNTER -l "Network Interface(${interface})Bytes Sent/sec") fi To this. bytes_in=$(${pluginlocation}/check_nt -H ${host} -p ${insertport} -s ${password} -v COUNTER -l "Network Adapter(${interface})Bytes Received/sec") bytes_out=$(${pluginlocation}/check_nt -H ${host} -p ${insertport} -s ${password} -v COUNTER -l "Network Adapter(${interface})Bytes Sent/sec") else # Without password bytes_in=$(${pluginlocation}/check_nt -H ${host} -p ${insertport} -v COUNTER -l "Network Adapter(${interface})Bytes Received/sec") bytes_out=$(${pluginlocation}/check_nt -H ${host} -p ${insertport} -v COUNTER -l "Network Adapter(${interface})Bytes Sent/sec")


Good !

This shell script uses check_nt to check both Bytes Sent and Bytes Received counters in one place. My understanding is that it is lacking the ability to set Warning and Critical thresholds. For that, I'm planning to user check_nt. My biggest challenge was to get NIC naming work. Here is what worked for me: ./check_win_net_usage.sh –H –p 12489 –i “Intel[R] 82579LM Gigabit Network Connection” And for thresholds, I used ./check_nt –H –p 12489 –v COUNTER –l “network interface(intel[r] 82579lm gigabit network connection)bytes sent/sec” –w 1000000 –c 3000000 and ./check_nt –H –p 12489 –v COUNTER –l “network interface(intel[r] 82579lm gigabit network connection)bytes received/sec” –w 1000000 –c 3000000
