![]() ![]() ![]() Returns the log events 3 lines before and after the line which included the term "example". grep Command Line: grep -B 3 -i "example".While there is no query language equivalent operation, you can search surrounding messages. Returns the log events 3 lines before the line which included the term "example". Sumo Equivalent: No equivalent operation.grep Command Line: grep -A 3 -i "example".Returns the log events 3 lines after the line which included the term "example". Sumo Equivalent: _sourceName=*/log_file AND " string ".Sumo Equivalent: _sourceName=*/log_file | parse regex "(start.*end)" | fields - sampleįinds all words which match the term "string" in a file named "log_file".Using regex, returns all events where a particular pattern is present on the log line. ![]() Sumo Equivalent: _sourceName=*/log_file AND "literal_string" | parse regex "(?literal_string)" | fields - sample.grep Command Line: grep "literal_string".Returns all log lines containing the term "literal_string" (case sensitive) in a file named log_file. Sumo Equivalent: _sourceName=*/log_* AND "string".Returns all log lines containing the word "string" (case insensitive) in a file that starts with "log_" in its name. Sumo Equivalent: _sourceName=*/log_file AND "string".Returns all log lines containing the term "string" (case insensitive) in a file named log_file. Sumo Equivalent: _sourceName=*/log_file.In Sumo, you must paginate through the results, but you can also search for ALL log files across your stack which share the same name. Returns the contents of a file named log_file for a specific timeframe. You should still follow the seven search rules to live by. We recommend that search your data using the _sourceCategory metadata tag, but you’ll see that the examples below use the _sourceName metadata tag because _sourceName should reflect the full canonical path of the file, which is typically what you use when greping files. (?#find) (?P\b. ), (?P\b.Remember that Sumo Logic queries are time-constrained. Groups can be named (assume a file of lastname, firstname altered using "preg_replace()") disallow digit AND whitespace occurrences - ? * rest of phone number means not digit OR whitespace, both match \s whitespace (space, tab, vtab, newline) \W, \D, or \S, (NOT word, digit, or whitespace) ) shorthand classes \w "word" character (letter, digit, or underscore) \d digit gr y match gray or grey match any letter or digit (In always escape. Use \ to search for these special characters:Ĭ: \\windows matches c:\windows alternatives - | (OR) cat|dog match cat or dog order matters if short alternative is part of longer id|identity matches id or identityĪs soon as 1st alternative matches identity|id matches id or identity order longer to shorter when alternatives overlap (To match whole words, see scope and groups.) character classes - or match any vowel match a NON vowel r ng match ring, w rangle, sp rung, etc. REGEX Cheat Sheet GREP cheat sheet characters - what to seek ring matches ring, sp ringboard, ringtone, etc. ![]()
