Filesystem monitoring
- Product information
- Release notes
Overview
filesystem extension, monitor your files on Windows and Linux OneAgent installations.
Targeting can be done by host, host group, management zone or environment. Tags can be applied to segregate your configurations (100 configurations maximum).
For each path check, Dynatrace will create an entity and link it to the matching host. This way, extension filtering and tagging is possible to view your data. The same can be done with alerts.
Checks can be disabled for specific days and at specific times.
Metrics:
-
File count: Number of files matching a pattern
-
File age count: Number of files matching a pattern and an age
-
File age: Age of a specific file (oldest or newest when returning more than 1 file)
-
File size: Size of the files in bytes
-
Mount point: Is a mount point mounted on Unix NFS
Use cases
- Monitor count of files and directories within a specific directory
- Check the newest or oldest file in a directory
- Verify if a file exists on a schedule
- Verify if a mount is present
- Check the count of files over a certain age
- Validate if a file is the proper size
