cri stage

The cri stage is a parsing stage that reads the log line using the standard CRI logging format.

Schema

yaml
cri: {}

Unlike most stages, the cri stage provides no configuration options and only supports the specific CRI log format. CRI specifies log lines log lines as space-delimited values with the following components:

  1. time: The timestamp string of the log
  2. stream: Either stdout or stderr
  3. log: The contents of the log line

No whitespace is permitted between the components. In the following example, only the first log line can be properly formatted using the cri stage:

"2019-01-01T01:00:00.000000001Z stderr P test\ngood"
"2019-01-01 T01:00:00.000000001Z stderr testgood"
"2019-01-01T01:00:00.000000001Z testgood"

Examples

For the given pipeline:

yaml
- cri: {}

Given the following log line:

"2019-04-30T02:12:41.8443515Z stdout xx message"

The following key-value pairs would be created in the set of extracted data:

  • content: message
  • stream: stdout
  • timestamp: 2019-04-30T02:12:41.8443515
