2023-03-06stats: fix node name compare error when updating stats segmentXiaoming Jiang1-1/+1

2022-11-30stats: add boot time in stats segmentOle Troan1-0/+2
Write time into /sys/boottime on VPP start. This allows a stateless control plane agent to validate if it's reconnecting to the same VPP instance. Type: improvement Signed-off-by: Ole Troan <ot@cisco.com> Change-Id: Iba7f334339c46142045e43da6efab11612e7b9c0 Signed-off-by: Ole Troan <ot@cisco.com>
2022-05-19stats: fix collector updates of symlinksArthur de Kerhor1-3/+9
A node name is not bound to a node index. For example, if an interface is deleted and re-added, the indexes of its nodes "<itfc_name>-tx" and "<itfc_name>-output" may change. Thus, when the collector updates the nodes stats, it should first delete all the symlinks for nodes that have changed their names before adding new symlinks. Otherwise, it could attempt to add already existing symlinks or delete valid ones. Example of a series of command that triggers a crash in the assert `ASSERT (node_data[i].symlinks[j] != CLIB_U32_MAX);`: ``` create loopback interface create loopback interface ``` Wait for the nodes stats to update, then: ``` delete loopback interface intfc loop0 delete loopback interface intfc loop1 create loopback interface create loopback interface ``` Type: fix Change-Id: Ief8e7135e5c02dc6bc64dc94b76cff21ea9ab3a9 Signed-off-by: Arthur de Kerhor <arthurdekerhor@gmail.com>
