  • What Grafana version and what operating system are you using?
    grafana v8.5.5

  • What are you trying to achieve?
    I try to display the job newest status in the table line.

  • How are you trying to achieve it?
    The data source is loki. I have some log lines from the syslog and I use the query {job=“app”}|pattern “<>HPCTRACE: <>: <_>: ”|line_format “{{.message}}”
    and choose the last value for the message by the group by in transform.

  • What happened?
    the message is not correct, because it is sort by the character rather than time stamp order.

  • What did you expect to happen?
    I want to display the last one message by timestamp order.
