Invoke-IcingaCheckTCP¶
Description¶
Checks the connection for an address and a range of ports and fetches the connection status including the time require to connect.
Invoke-IcingaCheckTCP connects to a provided address and a single or a range of ports and determines if the connection was successful or not. In addition the time for a successful connection is measured.
By default the plugin will return [CRITICAL] if the connection is not possible, can how ever be changed by the
-Negate argument which will return [CRITICAL] if the connection is possible.
In addition you can measure the connection time and alert by using -Warning or -Critical.
Permissions¶
No special permissions required.
Arguments¶
| Argument | Type | Required | Default | Description |
|---|---|---|---|---|
| Address | String | false | The IP address or FQDN of the target host | |
| Ports | Array | false | @() | A single or a list of ports to check on the target address |
| Negate | SwitchParameter | false | False | By default the plugin will return [CRITICAL] in case connections to a port are not possible. By setting this argument, the plugin will return [CRITICAL] for successful connections instead |
| Warning | Object | false | A warning threshold for the connection time in seconds. Allows the usage of unit additions, like 100ms. Allowed units: ms, s, m, h, d, w, M, y |
|
| Critical | Object | false | A critical threshold for the connection time in seconds. Allows the usage of unit additions, like 100ms. Allowed units: ms, s, m, h, d, w, M, y |
|
| NoPerfData | SwitchParameter | false | False | Disables the performance data output of this plugin. Default to FALSE. |
| Verbosity | Object | 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. |
