ystats

ystats subscribes to the live statistics of a running yuno and redraws them on a fixed interval. Where ycommand sends one request and prints one response, ystats keeps an open subscription and refreshes — use it to watch counters move (throughput, queue depth, connection counts) while a system is under load.

Usage¶

ystats --url ws://host:port [options]

# Watch the logcenter's stats, refreshing every 2 seconds
ystats --url ws://127.0.0.1:1991 --yuno_role logcenter -t 2

# Watch a specific statistic and a gobj attribute
ystats -s txMsgs -a connected -g my_tcp_server

Run ystats --help for the full flag list.

Authentication uses the same OAuth2 / OIDC flags as ycommand (--issuer/-I, --token-endpoint/-T, --end-session-endpoint/-E, --client-id/-Z, --user_id/-x, --user_passw/-X, --jwt/-j) — see Authentication (OAuth2 / OIDC).
