21 | - XS708E
22 | - GS308E
23 | - GS116Ev2

27 | - JGS524PE
28 | 
29 | ## Install
30 | Download from [release page](https://github.com/dalance/prosafe_exporter/releases/latest), and extract to any directory ( e.g. `/usr/local/bin` ).
31 | See the example files in `example` directory as below.
32 | 
33 | | File                             | Description                  |
34 | | -------------------------------- | ---------------------------- |
35 | | example/prosafe_exporter.service | systemd unit file            |
36 | 
37 | 
38 | If the release build doesn't fit your environment, you can build and install from source code.
39 | 
40 | ```
41 | cargo install prosafe_exporter
42 | ```
43 | 
44 | ## Usage
45 | 
46 | ```
47 | prosafe_exporter --web.listen-address=":9493"
48 | ```
49 | 
50 | The default listen port is 9493.
51 | It can be changed by `--web.listen-address` option.
52 | 
53 | The ProSAFE switches need to have the Switch Management Mode set to "Web browser and Plus Utility" for the exporter to work correctly.
54 | 
55 | ## Prometheus Server Configuration
56 | 
57 | The target switches of prosafe_exporter can be configured by the pair of hostname and network interface name ( e.g. `switch1:eth0` ).
58 | The network interface must be belonged to the same subnet as the switch.
59 | 
60 | The Prometheus server configuration is like [SNMP exporter](https://github.com/prometheus/snmp_exporter).
61 | The example of a configuration is below:
62 | 
63 | ```yaml
64 | - job_name: 'prosafe'
65 |   static_configs:
66 |       - targets: ['switch1:eth0', '192.128.0.100:enp1s0', 'switch2:*'] # target switches by hostname:if_name.
67 |   metrics_path: /probe
68 |   relabel_configs:
69 |     - source_labels: [__address__]
70 |       target_label: __param_target
71 |     - source_labels: [__param_target]
72 |       target_label: instance
73 |     - target_label: __address__
74 |       replacement: 127.0.0.1:9493 # The prosafe_exporter's real hostname:port.
75 | ```
76 | 
77 | `if_name` can be `*`. If `*` is used, prosafe_exporter will search an accessible network interface automatically.
78 | 
79 | ## Query Example
80 | 
81 | Outgoing data rate of `port1` on `switch1:eth0` is below.
82 | 
83 | ```
84 | rate(prosafe_transmit_bytes_total{instance="switch1:eth0", port="1"}[1m])
85 | ```
86 |
