Arguments

Argument Type Required Default Description
Warning Object false Used to specify the webrequest response time warning threshold in seconds, everything past that threshold is considered a WARNING.
Critical Object false Used to specify the webrequest response time critical threshold in seconds, everything past that threshold is considered a CRITICAL.
Url Array false @() Used to specify the URL of the host to check http as string. Use 'http://' or 'https://' to actively chose a protocol. Likewise ':80' or any other port number to specify a port, etc.
VHost String false Used to specify a VHost as string.
Headers Array false @() Used to specify headers as Array. Like: -Headers 'Accept:application/json'
Timeout Int32 false 10 Used to specify the timeout in seconds of the webrequest as integer. The default is 10 for 10 seconds.
Username String false Used to specify a username as string to authenticate with. Authentication is only possible with 'https://'. Use with: -Password
Password SecureString false Used to specify a password as securestring to authenticate with. Authentication is only possible with 'https://'.Use with: -Username
ProxyUsername String false Used to specify a proxy username as string to authenticate with. Use with: -ProxyPassword & -ProxyServer
ProxyPassword SecureString false Used to specify a proxy password as securestring to authenticate with. Use with: -ProxyUsername & -ProxyServer
ProxyServer String false Used to specify a proxy server as string to authenticate with.
Content Array false @() Used to specify an array of regex-match-strings to match against the content of the webrequest response.
StatusCode Array false @()
Minimum Int32 false -1
Negate SwitchParameter false False A switch used to invert check results.
AddOutputContent SwitchParameter false False Adds the returned content of a website to the plugin output for debugging purpose
ConnectionErrAsCrit SwitchParameter false False By default the plugin will return UNKNOWN in case a connection to a webserver is not possible. By using this
flag, the result will be modified from UNKNOWN to CRITICAL
NoPerfData SwitchParameter false False Used to disable PerfData.
Verbosity Int32 false 0 Changes the behavior of the plugin output which check states are printed:
0 (default): Only service checks/packages with state not OK will be printed
1: Only services with not OK will be printed including OK checks of affected check packages including Package config
2: Everything will be printed regardless of the check state
3: Identical to Verbose 2, but prints in addition the check package configuration e.g (All must be [OK])
ThresholdInterval String Change the value your defined threshold checks against from the current value to a collected time threshold of the Icinga for Windows daemon, as described here. An example for this argument would be 1m or 15m which will use the average of 1m or 15m for monitoring.
