You can get troubleshooting information from the HAProxy Enterprise nodes' or Stick Table Aggregator's
stats socket CLI, or by launching the Stick Table Aggregator process with specific arguments.
HAProxy Enterprise Runtime API
Check the status of HAProxy Enterprise peers
$ sudo socat stdio unix-connect:/var/run/hapee-2.0/hapee-lb.sock \ <<< "show peers" | head -2
The last_status of the Stick Table Aggregator peer should be ESTA.
Stick Table Aggregator CLI
Display debugging information about
$ sudo socat stdio /tmp/stktagg.socket <<< "show aggrs"
aggregations myaggr table 'mytable.uncombined' aggregated to 'mytable.aggr' (expire: 3600000 nb_entries: 1) update: 0xb598160 used: 0xb598170 peer 'hapee1' (0) state: 0x7 push: 0xb598160 ack: 0xb598160 sync: 0xb597ff0 peer 'hapee2' (1) state: 0x7 push: 0xb598160 ack: 0xb598160 sync: 0xb597ff0
Gives the list of peers and aggregate tables for all aggregations sections in the configuration file.
The following fields are available:
Displays the last key that was updated in the Stick Table Aggregator table.
Displays the last key that was pushed to a given peer.
Always the same value as
Protocol state of the peers session with a given peer.
A working peers session has a state of 0x7.
Display the Stick Table Aggregator's aggregate stick table:
show table <aggregation ID> <table name>
For each key, the aggregate entry and the entry sent by each peer are displayed.
Expired entries remain visible, and are reused when the same key is reused.
$ sudo socat stdio /tmp/stktagg.socket <<< "show table myaggr mytable.aggr" key=127.0.0.1 http_req_rate=(3600000)=1 exp=3599209 hapee1: http_req_rate=(3600000)=1 exp=3599209 hapee2: http_req_rate=(3600000)=0 expired
$ sudo socat stdio /tmp/stktagg.socket <<< "help"
Stick Table Aggregator process arguments
By default, the Stick Table Aggregator starts as a daemon with the following arguments:
$ /opt/hapee-extras/sbin/hapee-stktagg \ -f /etc/hapee-extras/hapee-stktagg.cfg \ -p /var/run/hapee-extras/hapee-stktagg.pid \ -D
Start in debug mode and read a specific configuration file at startup
$ /opt/hapee-extras/sbin/hapee-stktagg -f <configuration file> -d
$ /opt/hapee-extras/sbin/hapee-stktagg -f /etc/hapee-extras/hapee-stktagg.cfg -d cfg_agg_params_compute (2 2 0) Starting event loop hapee1 peer: received new definition message for 'mytable.uncombined' stick-table build_new_agg: peer: hapee1 from: 'mytable.uncombined' -> to 'mytable.aggr' id: 1 hapee1 peer: received new definition message for 'mytable.aggr' stick-table hapee2 peer: received new definition message for 'mytable.uncombined' stick-table hapee2 peer: received new definition message for 'mytable.aggr' stick-table

$ sudo /opt/hapee-extras/sbin/hapee-stktagg -f <configuration file> -D
