| Configuration Variable | Default (if not set at all) | Controls |
|---|
fastping_timeout | 300 | Controls the -t setting for fping which is: -tn Initial target timeout in milliseconds (default 500). In the default mode, this is the amount of time that fping waits for a response to its first request. Successive timeouts are multiplied by the backoff factor. |
|---|
|
| fastping_packet | 56 | Controls the -b setting for fping which is: -bn Number of bytes of ping data to send. The minimum size (normally 12) allows room for the data that fping needs to do its work (sequence number, timestamp). The reported received data size includes the IP header (normally 20 bytes) and ICMP header (8 bytes), so the minimum total size is 40 bytes. Default is 56, as in ping. Maximum is the theoretical maximum IP datagram size (64K), though most systems limit this to a smaller, system-dependent number. |
|---|
If this is set to < 24 it will be set to 24. |
| fastping_retries | 3 | Controls the -r setting for fping which is: -rn Retry limit (default 3). This is the number of times an attempt at pinging a target will be made, not including the first try. |
|---|
|
| fastping_count | 3 | Controls the -C setting for fping which is: -C Similar to -c, but the per-target statistics are displayed in a format designed for automated response-time statistics gathering. For example: % fping -C 5 -q somehost somehost : 91.7 37.0 29.2 - 36.8 shows the response time in milliseconds for each of the five requests, with the "-" indicating that no response was received to the fourth request. |
|---|
|
| fastping_sleep | 60 | The number of seconds fpingd will sleep before running another ping cycle + random(10) |
| fastping_node_poll | 300200 | The number of nodes to ping in one invocation of fping. We strongly recommend that this value is set to no more than 250; otherwise you risk exceeding the linux command line length limits which will cause incorrect operation of fpingd.pl. |
