checknetwork
These network checks use WMI Raw counters to calculate values over a given timeperiod.
This is much more accurate than taking Formatted WMI values.
ARG1 Specify the network interface the stats are collected for. If set to . all interfaces will be included.
To include multiple interfaces separate them with a | or specify a common identifier eg part of an IP Address or MAC Address. This uses a regular expression so take care to
specify exactly what you want. eg "LAN0" or "192.168.0.1" or "192.168.0" or "LAN0|LAN2" or "." or "08:00:27:85:CE:6D" or "08:00:27"
To specify a network interface you can use either the Connection Name (as seen in Control Panel), IP Address (IPv4 or IPV6) or MAC Address. You can also use the name of the network adaptors as seen from WMI which is similar to what is seen in the output of the ipconfig/all command on Windows. However, it is not exactly the same and can be tricky since this uses a regular expression. Run without -a to show the interface
names, IP Addresses, MAC Addresses. Typically you need to use '' around the adapter name when specifying.
DELAY (optional) specifies the number of seconds over which the utilisation is calculated. The longer you can make this without timing out, the more accurate it will be. If specifying longer values. You may also need to use the -t parameter to set a longer script timeout. Only valid if also specifying --nokeepstate ie you are not using the state keeping feature. We recommend that you do keep state and hence do not use --nokeepstate.
WARN/CRIT can be used as described below.
Valid Warning/Critical Fields are: CurrentBandwidth (Default), _PacketsSentPersec, _PacketsReceivedPersec, OutputQueueLength, PacketsReceivedErrors, _BytesSentPersec, _BytesReceivedPersec, _SendBytesUtilisation, _ReceiveBytesUtilisation
BYTEFACTOR defaults to 1000 for this mode. You can override this if you wish.
Note:
This check does up to 3 WMI queries so it may be slow. You might need to use the -t option. Since 2 of the WMI queries are relatively static, their results are cached and you can set the refresh period for this data using --joinexpiry.
