It returns whether all the format strings can be parsed correctly\&. It will load plugins unless specified otherwise\&. .sp This is useful to check for any trace event format strings which may contain some internal kernel function references which cannot be decoded outside of the kernel\&. This may mean that either the unparsed format strings of the trace events need to be changed or that a plugin needs to be created to parse them\&. .SH "OPTIONS" .sp \fB\-N\fR \- Don\(cqt load plugins .PP \fB\-\-verbose\fR[=\fIlevel\fR] .RS 4 Set the log level\&. Supported log levels are "none", "critical", "error", "warning", "info", "debug", "all" or their identifiers "0", "1", "2", "3", "4", "5", "6"\&. Setting the log level to specific value enables all logs from that and all previous levels\&.
