HAProxy stat MetricSetedit

This is the stat metricset of the haproxy module.

Official documentation for fieldsedit

A list of the stat fields along with a basic description can be found here:

http://www.haproxy.org/download/1.6/doc/management.txt

The following documentation bellow is an extract from the URL above, more specifically from section "9.1. CSV format"

In brackets after each field name are the types which may have a value for
that field. The types are L (Listeners), F (Frontends), B (Backends), and
S (Servers).

  0. pxname [LFBS]: proxy name
  1. svname [LFBS]: service name (FRONTEND for frontend, BACKEND for backend,
     any name for server/listener)
  2. qcur [..BS]: current queued requests. For the backend this reports the
     number queued without a server assigned.
  3. qmax [..BS]: max value of qcur
  4. scur [LFBS]: current sessions
  5. smax [LFBS]: max sessions
  6. slim [LFBS]: configured session limit
  7. stot [LFBS]: cumulative number of connections
  8. bin [LFBS]: bytes in
  9. bout [LFBS]: bytes out
 10. dreq [LFB.]: requests denied because of security concerns.
     - For tcp this is because of a matched tcp-request content rule.
     - For http this is because of a matched http-request or tarpit rule.
 11. dresp [LFBS]: responses denied because of security concerns.
     - For http this is because of a matched http-request rule, or
       "option checkcache".
 12. ereq [LF..]: request errors. Some of the possible causes are:
     - early termination from the client, before the request has been sent.
     - read error from the client
     - client timeout
     - client closed connection
     - various bad requests from the client.
     - request was tarpitted.
 13. econ [..BS]: number of requests that encountered an error trying to
     connect to a backend server. The backend stat is the sum of the stat
     for all servers of that backend, plus any connection errors not
     associated with a particular server (such as the backend having no
     active servers).
 14. eresp [..BS]: response errors. srv_abrt will be counted here also.
     Some other errors are:
     - write error on the client socket (won't be counted for the server stat)
     - failure applying filters to the response.
 15. wretr [..BS]: number of times a connection to a server was retried.
 16. wredis [..BS]: number of times a request was redispatched to another
     server. The server value counts the number of times that server was
     switched away from.
 17. status [LFBS]: status (UP/DOWN/NOLB/MAINT/MAINT(via)...)
 18. weight [..BS]: total weight (backend), server weight (server)
 19. act [..BS]: number of active servers (backend), server is active (server)
 20. bck [..BS]: number of backup servers (backend), server is backup (server)
 21. chkfail [...S]: number of failed checks. (Only counts checks failed when
     the server is up.)
 22. chkdown [..BS]: number of UP->DOWN transitions. The backend counter counts
     transitions to the whole backend being down, rather than the sum of the
     counters for each server.
 23. lastchg [..BS]: number of seconds since the last UP<->DOWN transition
 24. downtime [..BS]: total downtime (in seconds). The value for the backend
     is the downtime for the whole backend, not the sum of the server downtime.
 25. qlimit [...S]: configured maxqueue for the server, or nothing in the
     value is 0 (default, meaning no limit)
 26. pid [LFBS]: process id (0 for first instance, 1 for second, ...)
 27. iid [LFBS]: unique proxy id
 28. sid [L..S]: server id (unique inside a proxy)
 29. throttle [...S]: current throttle percentage for the server, when
     slowstart is active, or no value if not in slowstart.
 30. lbtot [..BS]: total number of times a server was selected, either for new
     sessions, or when re-dispatching. The server counter is the number
     of times that server was selected.
 31. tracked [...S]: id of proxy/server if tracking is enabled.
 32. type [LFBS]: (0=frontend, 1=backend, 2=server, 3=socket/listener)
 33. rate [.FBS]: number of sessions per second over last elapsed second
 34. rate_lim [.F..]: configured limit on new sessions per second
 35. rate_max [.FBS]: max number of new sessions per second
 36. check_status [...S]: status of last health check, one of:
        UNK     -> unknown
        INI     -> initializing
        SOCKERR -> socket error
        L4OK    -> check passed on layer 4, no upper layers testing enabled
        L4TOUT  -> layer 1-4 timeout
        L4CON   -> layer 1-4 connection problem, for example
                   "Connection refused" (tcp rst) or "No route to host" (icmp)
        L6OK    -> check passed on layer 6
        L6TOUT  -> layer 6 (SSL) timeout
        L6RSP   -> layer 6 invalid response - protocol error
        L7OK    -> check passed on layer 7
        L7OKC   -> check conditionally passed on layer 7, for example 404 with
                   disable-on-404
        L7TOUT  -> layer 7 (HTTP/SMTP) timeout
        L7RSP   -> layer 7 invalid response - protocol error
        L7STS   -> layer 7 response error, for example HTTP 5xx
 37. check_code [...S]: layer5-7 code, if available
 38. check_duration [...S]: time in ms took to finish last health check
 39. hrsp_1xx [.FBS]: http responses with 1xx code
 40. hrsp_2xx [.FBS]: http responses with 2xx code
 41. hrsp_3xx [.FBS]: http responses with 3xx code
 42. hrsp_4xx [.FBS]: http responses with 4xx code
 43. hrsp_5xx [.FBS]: http responses with 5xx code
 44. hrsp_other [.FBS]: http responses with other codes (protocol error)
 45. hanafail [...S]: failed health checks details
 46. req_rate [.F..]: HTTP requests per second over last elapsed second
 47. req_rate_max [.F..]: max number of HTTP requests per second observed
 48. req_tot [.F..]: total number of HTTP requests received
 49. cli_abrt [..BS]: number of data transfers aborted by the client
 50. srv_abrt [..BS]: number of data transfers aborted by the server
     (inc. in eresp)
 51. comp_in [.FB.]: number of HTTP response bytes fed to the compressor
 52. comp_out [.FB.]: number of HTTP response bytes emitted by the compressor
 53. comp_byp [.FB.]: number of bytes that bypassed the HTTP compressor
     (CPU/BW limit)
 54. comp_rsp [.FB.]: number of HTTP responses that were compressed
 55. lastsess [..BS]: number of seconds since last session assigned to
     server/backend
 56. last_chk [...S]: last health check contents or textual error
 57. last_agt [...S]: last agent check contents or textual error
 58. qtime [..BS]: the average queue time in ms over the 1024 last requests
 59. ctime [..BS]: the average connect time in ms over the 1024 last requests
 60. rtime [..BS]: the average response time in ms over the 1024 last requests
     (0 for TCP)
 61. ttime [..BS]: the average total session time in ms over the 1024 last
     requests
