The exporter watches files, providing the last modified date, file size, and a few system metrics for the Prometheus.
Written in Rust
Built using Prometheus exporter base
| Metric name | Description |
|---|---|
| filewatcher_file_modified | File last modified timestamp |
| filewatcher_file_size | File size in bytes |
| mem_total | Total amount of server memory in bytes |
| mem_used | Total used memory in bytes |
| mem_swap_total | Swap size in bytes |
| mem_swap_used | Used swap size in bytes |
| disk_free | Free disk space in bytes (for each mount point in the system) |
| disk_total | Total dis size in bytes (for each mount point in the system) |
filewatcher_exporter -p 9104 -h 127.0.0.1 -t "/var/log/nginx/error.log;/var/log/nginx/access.log"
-p [port] - port number, default 9104
-h [host] - hostname, default 0.0.0.0
-v - verbouse
-t [targets] - list of files to watch, separated by ;NOTE: Use Rust nightly version
