@global.log_error_suppression_list accepts a comma-separated list of error-codes that should not be included in the error-log.
Events with a severity of System or Error can not be filtered in this way and will always be forwarded to the log-sinks.
This provides simple filtering for cases where the flexibility of the loadable filter-language is not needed. (The same engine is used however, just with a more limited interface.)
For this filtering to be active, @global.log_error_services has to feature "log_filter_internal", as it does by default. When that is the case, one or both of log_error_verbosity and this variable may be used. Only one of "log_filter_internal" and "log_filter_dragnet" should be used at a time.
The semantics follow that of our system variables; that is to say, when called with update==false, the function acts as a check-function that validates the entire list given to it; when called with update==true, it creates filter-rules from the list items. This way, we either create all rules, or no rules, rather than ending up with an incomplete rule-set when we encounter a problem in the input.
The return value encodes the location in the argument where the failure occurred, like so:
| list | list of error-codes that should not appear in the error-log |
| update | false: verify list only true: create filtering rules from suppression list |
| 0 | success |
| !0 | failure (see above) |
| int log_builtins_filter_run | ( | log_filter_ruleset * | ruleset, |
| log_line * | ll | ||
| ) |
Apply all matching rules from a filter rule set to a given log line.
| ruleset | rule-set to apply |
| ll | the current log line |
| int | number of matched rules |
| int log_builtins_filter_update_verbosity | ( | int | verbosity | ) |
This is part of the 5.7 emulation: If –log_error_verbosity is changed, we generate an artificial filter rule from it here.
For this filtering to be active, @global.log_error_services has to feature "log_filter_internal", as it does by default. When that is the case, one or both of log_error_verbosity and log_error_suppression_list (see below) may be used. Only one of "log_filter_internal" and "log_filter_dragnet" should be used at a time.
| verbosity | log_error_verbosity style, range(1,3) 1:errors, 2:+=warnings, 3:+=notes |
