srv_name: Server label.
srv_addr: Server IP address.
srv_op_state: Server operational state (UP/DOWN/...).
In source code: SRV_ST_*.
0 = SRV_ST_STOPPED
The server is down.
1 = SRV_ST_STARTING
The server is warming up (up but
throttled).
2 = SRV_ST_RUNNING
The server is fully up.
3 = SRV_ST_STOPPING
The server is up but soft-stopping
(eg: 404).
srv_admin_state: Server administrative state (MAINT/DRAIN/...).
In source code: SRV_ADMF_*.
The state is actually a mask of values :
0x01 = SRV_ADMF_FMAINT
The server was explicitly forced into
maintenance.
0x02 = SRV_ADMF_IMAINT
The server has inherited the maintenance
status from a tracked server.
0x04 = SRV_ADMF_CMAINT
The server is in maintenance because of
the configuration.
0x08 = SRV_ADMF_FDRAIN
The server was explicitly forced into
drain state.
0x10 = SRV_ADMF_IDRAIN
The server has inherited the drain status
from a tracked server.
srv_uweight: User visible server's weight.
srv_iweight: Server's initial weight.
srv_time_since_last_change: Time since last operational change.
srv_check_status: Last health check status.
srv_check_result: Last check result (FAILED/PASSED/...).
In source code: CHK_RES_*.
0 = CHK_RES_UNKNOWN
Initialized to this by default.
1 = CHK_RES_NEUTRAL
Valid check but no status information.
2 = CHK_RES_FAILED
Check failed.
3 = CHK_RES_PASSED
Check succeeded and server is fully up
again.
4 = CHK_RES_CONDPASS
Check reports the server doesn't want new
sessions.
srv_check_health: Checks rise / fall current counter.
srv_check_state: State of the check (ENABLED/PAUSED/...).
In source code: CHK_ST_*.
The state is actually a mask of values :
0x01 = CHK_ST_INPROGRESS
A check is currently running.
0x02 = CHK_ST_CONFIGURED
This check is configured and may be
enabled.
0x04 = CHK_ST_ENABLED
This check is currently administratively
enabled.
0x08 = CHK_ST_PAUSED
Checks are paused because of maintenance
(health only).
srv_agent_state: State of the agent check (ENABLED/PAUSED/...).
In source code: CHK_ST_*.
This state uses the same mask values as
"srv_check_state", adding this specific one :
0x10 = CHK_ST_AGENT
Check is an agent check (otherwise it's a
health check).
bk_f_forced_id: Flag to know if the backend ID is forced by
configuration.
srv_f_forced_id: Flag to know if the server's ID is forced by
