General information about the CQ Watcher is available in the README.
The number of CLs in Skia's CQ are beyond the threshold. Take a look at the dry run queue and the commit queue and try to determine why CLs have piled up there.
The specified trybot has been running beyond the threshold. Look for which CLs this happened in from the cloud logs. Try to determine why it took so long: Was it in pending state? is it a one-off event? is this the new norm and the threshold needs to be increased?
The number of triggered CQ trybots by atleast one CL is beyond the threshold. Look for which CLs this happened in from the cloud logs. This alert has been created to detect problems like crbug/656756.
