PTX EVO boxes are sending telemetry data for Label Switched Paths (LSP) even when no active RSVP LSPs are configured. This data is incorrectly parsed by the customer's collector, leading to excessive logging and "no LSP found" messages.
PTX EVO boxes send data for the sensor /junos/services/label-switched-path/usage even when no LSPs are configured.
If there is a segment routing (SR) configuration, it will cause the issue. The LSP statistics are taking count from SR, which may lead to this problem.
Config:
device> show configuration services analytics streaming-server paragon { remote-address 10.1.1.1; remote-port 4000; } sensor lsp { server-name paragon; export-name paragon; resource /junos/services/label-switched-path/usage/; }
Sample Command Output:
No Active LSP on the box
