sysutil is a library which implementats the gRPC service Diagnostics and shares the diagnostics functions between TiDB and PD.

The semantics of the log search service is: search for local log files, and filter using predicates, and then return the matched results.

The following are the predicates that the log interface needs to process:

start_time: start time of the log retrieval (Unix timestamp, in milliseconds). If there is no such predicate, the default is 0.
end_time:: end time of the log retrieval (Unix timestamp, in milliseconds). If there is no such predicate, the default is int64::MAX.
pattern: filter pattern determined by the keyword. For example, SELECT * FROM tidb_cluster_log WHERE "%gc%" %gc% is the filtered keyword.
level: log level; can be selected as DEBUG/INFO/WARN/WARNING/TRACE/CRITICAL/ERROR
limit: the maximum of logs items to return, preventing the log from being too large and occupying a large bandwidth of the network.. If not specified, the default limit is 64k.
