QueryString Class
Define a QueryString.
Example
ts
new logs.QueryDefinition(this, 'QueryDefinition', {
queryDefinitionName: 'MyQuery',
queryString: new logs.QueryString({
fields: ['@timestamp', '@message'],
parseStatements: [
'@message "[*] *" as loggingType, loggingMessage',
'@message "<*>: *" as differentLoggingType, differentLoggingMessage',
],
filterStatements: [
'loggingType = "ERROR"',
'loggingMessage = "A very strange error occurred!"',
],
statsStatements: [
'count(loggingMessage) as loggingErrors',
'count(differentLoggingMessage) as differentLoggingErrors',
],
sort: '@timestamp desc',
limit: 20,
}),
});
python
logs.QueryDefinition(self, "QueryDefinition",
query_definition_name="MyQuery",
query_string=logs.QueryString(
fields=["@timestamp", "@message"],
parse_statements=["@message \"[*] *\" as loggingType, loggingMessage", "@message \"<*>: *\" as differentLoggingType, differentLoggingMessage"
],
filter_statements=["loggingType = \"ERROR\"", "loggingMessage = \"A very strange error occurred!\""
],
stats_statements=["count(loggingMessage) as loggingErrors", "count(differentLoggingMessage) as differentLoggingErrors"
],
sort="@timestamp desc",
limit=20
)
)
java
