2021-06-01statsclient: fix retrieving stats typeVladimir Lavor1-1/+5
Signed-off-by: Vladimir Lavor <vlavor@cisco.com> Change-Id: Id51fa03ac69a2fc29aca5ff644178cdfcabe523c
2021-05-26statsclient: added symlinksVladimir Lavor1-2/+4
Symlink support based on https://gerrit.fd.io/r/c/vpp/+/31636 Added new stat types `CounterStat` and `CombinedCounterStat` which represent simple/combined value of a single item (interface, node) as a array of values by workers. Example: /if/names NameVector [local0 tap0 tap1] /if/ip6 SimpleCounterVector [[0 9 0] [0 25 3] [0 0 60] [0 0 0]] /interfaces/tap0/ip6 SimpleCounterVector [[9] [25] [0] [0]] /interfaces/tap1/ip6 SimpleCounterVector [[0] [3] [60] [0]] Field `Symlink` added to StatEntry to mark symlink stats. For stats v2 only Change-Id: Iadc825f3c42b05bfc9a91462dba8a0b0068c7cd6 Signed-off-by: Vladimir Lavor <vlavor@cisco.com>
2021-05-05statsclient: allow index as patternVladimir Lavor1-103/+134
* ListStats() returns stats identifiers containing the stat name and index * New method PrepareDirOnIndex(indexes...). Instead of the name filter it does not browse through all available indexes * Stats example shows how to get the last epoch value (added "e" or "epoch" command) Change-Id: Ibb15090fb0dfdb7f9b0ecf8ac07a5eb9a9ace8f8 Signed-off-by: Vladimir Lavor <vlavor@cisco.com>
2021-04-07Add statsclient options and fix wait for socketVladimir Lavor1-10/+44

2021-02-23Added asynchronous connection for stats socketVladimir Lavor1-30/+73
The stats socket now allows an option to connect asynchronously in the same manner as the api socket connection. New method AsyncConnectStats returns a channel where notificaitons of type ConnectionEvent will be sent. Fixed the stats reconnect procedure which sometimes failed to re-eneable the connection.

2020-09-22Reload stats socket when VPP restartsVladimir Lavor1-25/+100
The current implementation loads the stats socket and maps it to the memory. If VPP restarts, the socket file is recreated while the mapped data remain unchanged, silently failing since it does not get any updates. This change adds socket file monitoring which reconnects and remaps the socket file in such a case.

2020-03-20Fix statsclient for VPP 20.05-rc0 (master)v0.3.2Ondrej Fabry1-29/+32
- this change fixes panic that was occurring with recent VPP that was caused by incorrectly calculated vector length - converting returned vector length from uint64 to uint32 results in correct length value Change-Id: I76a4b9d147c3df3bea9d3e5ef5853e2809dc42e8 Signed-off-by: Ondrej Fabry <ofabry@cisco.com>
2019-10-03Optimizations for statsclientOndrej Fabry1-77/+196
- this dramatically improves performance for stats data collection - memory allocation is now done only when stat dirs change - updating prepared stat dir does not need to allocate memory - created integration test for testing stats client - added NumWorkerThreads and VectorRatePerWorker to SystemStats - added ReduceSimpleCounterStatIndex, ReduceCombinedCounterStatIndex for aggregating specific index Change-Id: I702731a69024ab5dd0832bb5cfe2773a987359e5 Signed-off-by: Ondrej Fabry <ofabry@cisco.com>

- RPC service client implementation for dumps requests now streams responses - RPC service generation is now enabled by default - examples now allow setting binapi socket address - input dir flag for binapi-generator will recursively look into dirs to support core/plugins in /usr/share/vpp/api - minor improvements in debug logs - add support for VPP 19.04 for statsclient Change-Id: I0939ee3aa6e9f850d073fc5c87aff4ccc56b0d70 Signed-off-by: Ondrej Fabry <ofabry@cisco.com>
