Logs

Everything your containers print, searchable in the console and followed from the CLI.

Updated 13 Oct 2026View as Markdown

Ops collects what every container of your project prints to stdout and stderr. There is nothing to install and nothing to configure.

Write JSON lines

A plain line is kept as its message. A line that is a JSON object is read field by field, and these fields are kept:

fieldused for
levelthe level filter: ERROR, WARN, INFO, DEBUG
message, or fields.messagethe text
targetwhere in the code it came from
fields.route, fields.status, fields.methodthe request it belongs to; route may also sit at the top

status and method count only inside fields, the way a tracing subscriber nests a line's fields. Any other field is dropped before it is stored. Email addresses, card numbers, tokens and similar values in a message are masked. Still, never log a password or a person's data on purpose.

With the Rust ops-sdk, set LOG_FORMAT=json in the service's secret group and the subscriber writes exactly this shape.

In the console

Logs shows the environment picked in the sidebar, newest first, with a histogram over the range. Filter by service, level, a search text and a time range; the filters apply as you change them.

From a terminal

sh
ops logs                          # the latest 200 lines
ops logs --level ERROR --since 1h
ops logs --grep timeout --limit 1000
ops logs -f                       # follow, Ctrl+C to stop
ops logs -f --env staging
flagwhat it does
--service <name>one service, written as the service column of the output shows it
--level <level>one level
--grep <text>lines whose message holds the text
--since <time>from a duration ago, such as 30s, 5m, 2h or 7d, or from an RFC 3339 time
--limit <n>at most n lines, 1 to 1000
--env <name>another environment than production
-fkeep following new lines
--interval <secs>how often -f asks, default 2

ops logs reads the project chosen with ops use. Pipe it into grep or awk: every line is the time, the level, the service and the message.
