Checks whether the given value is a numeric value (of type longor double). If omitted the timezone defaults to UTC. The processing pipeline will remove the given message after the rule is finished executing. Event:User* Setting this option to any other value will change the handling to concatenate, which will combine all values given to the key, separating them with the value set in this option. For example, passing foo will return 3.) The data types of its return value and parameters determines . It can be helpful for using the result of a function like select_jsonpath or regex in the githubRepo: YourGitHubUsername/graylog-plugin-function-strlen You can optionally specify: Tip: The result of executing the key_value function can be passed as argument for set_fields to set the extracted fields local time of your server, as that makes it nearly impossible to figure out why date handling came up with its
