Lists the routers that send HSRP Hello messages, keyed by the router's IP address.
| Property | Value |
|---|
| GUID | {47FB78D7-76F6-4AF0-D45A-7D9BA6E83762} |
| Layer | L7 Application |
| Input | Packets |
| Key type | IPv4 address (dotted decimal) |
| Implementation | Lua — hsrp-routers.lua, fed by hsrp-counter.lua (apps/analyzers/hsrp) |
| Trisul App | hsrp (install from Trisul Apps) |
| Bucket / Topper | 30 s / 300 s |
| Enabled by default | Yes, once the app is installed |
What it measures
- For every HSRP Hello (UDP 1985, op code 0),
hsrp-counter.lua sets the meter to 1 for the IP source address of the packet.
- The meter is a gauge, so a router that sent at least one Hello in the interval shows 1. A router that stops sending has no value for that interval.
- Use it to see which routers take part in HSRP. Use HSRP Hits for the Active/Standby state.
Keys
The router's IPv4 address in dotted decimal. This is not the Trisul hex host form, so these keys do not match keys in Hosts.
| Key | Meaning |
|---|
10.1.1.2 | Router with interface address 10.1.1.2 |
10.1.1.3 | Second router in the same HSRP group |
Special keys
| Key | Meaning |
|---|
SYS:GROUP_TOTALS | Receives the same gauge updates, so it is 1 whenever any router sent a Hello. |
