File Existence Monitor
The File Existence Monitor is a SAM component monitor included in several SAM application monitor template that you can assign to a target servers to test if a file exists at a specific location on that server.
By default, it uses the following ports:
- TCP port 445
- UDP port 445
Windows credentials with read access to the network share.
Agent-less or SolarWinds Platform agent for Windows requirements
Implementation of these components relies either on WMI or Windows File Share access to the target machine.
SolarWinds Platform agent for Linux requirements
Python implementation leverages native file system access directly from the python script running locally on the target agent machine. Due to the configuration settings, switching between agent-less and SolarWinds Platform agent for Linux will not establish a correct connection as the file path in UNC format will not work on a Linux-based computer. For details, see Configure Linux/Unix systems for monitoring by the SolarWinds Platform agent in SAM.
File Existence Monitor details
You can use wildcards in path statements. For example, specify
\\dumpserver\c$\dump\dumpfile*.* to check for all files that start with
The Component Type value for this component monitor, for use in alert variables, is 28. To learn more, see Use alerts to monitor your environment or watch a SolarWinds Lab Bits video, Automating Alert Trigger Actions.
If you receive a
There are currently no logon servers available to service the logon request message, try these workarounds:
- Add the IP address of the target node to the host file of your Main Polling Engine (usually the SolarWinds Platform server), or an Additional Polling Engine (APE), depending on where the node is assigned.
- Add the IP address of the assigned polling engine to the host file on the target machine, which can help bypass DNS issues.
