Tried to use `eval title=if(le_description, le_description, event_type)` doesn't work. How can I check if the record has the "le_description" if not, brings `event_type` instead? I have a json with multiple `events, inside this event I have "le_description", but, some record, doesn't have this "le_description" object, so, I don't have the "le_description". | rename account_id as "Account ID", timestamp as "Timestamp", context.display_name as "System", context.host_url as "Host URL", event_type as "Event Type", "title" as "Title", "application" as "Application", "le_url" as "URL" | table timestamp, le_description, "context.display_name", account_id, "event_type", "application", "le_url" Usage You can use this function with the eval, fieldformat, and where commands, and as part of eval expressions. There are two conditions based on which the query is executed : If method field is equal to DELETE, then âPASSâ should be assigned to the NEWFIELD If method field is not equal to DELETE,then â FAILâ should be assigned to the NEWFIELD. eval expression overwrite the values in that field. Then we have used the splunk eval command to implement this. My idea would be to create a new field 'finalprice' and use. In the statistics I would like to tell Splunk to use 'price II' if it exists, otherwise use 'price'. Now there will be a new field 'price II' in the eventstructure. If the field name already exists in your events, eval overwrites the value. Required arguments field Syntax: Description: A destination field name for the resulting calculated value. The arguments can be strings, multivalue fields or single value fields. If the field name that you specify matches a field name that already exists. in the past I used a lookup to add the field 'price' to my events. Syntax eval ',' .However, the fields disappear when I search from the past 5 minutes or so since there are no records.| stats by timestamp, events, application, event_type, account_id, context.display_name, Description This function takes one or more arguments and returns a single multivalue result that contains all of the values. if it is an IP address do something, if it is a hostname do something else. If I extend the time range to before a failover occurred, I get the desired format. In Splunk search query how to check if log message has a text or not Log message: message: T07:15:28,458+0000 comphub-lora-ingestor-0 vert.x-eventloop-thread-0 INFO .receiver.HonoReceiver - Connected successfully, creating telemetry consumer. I have a field to evaluate if the value of the field is an IP address or a hostname. When using the stat command, data is returned in the format provided below. Host = host2 source = /var/log/file.log sourcetype = service (index=product1 OR index=product2 OR (index=test_test sourcetype=product*)) ("event :kv-cluster/create-val" OR "event :transactor/standby") (host="host1" OR host="host2") | rex "(?i)\-ext \- \ Is it possible to display all cases of the below query, even if the count is zero? Currently, my query only returns the cases with at least 1 log generated. Mark as New Bookmark Message Subscribe to Message Mute Message Subscribe to RSS Feed . what is the command to check if a field exists in one column but not the other for example, to count the '10.2.3. You can chain multiple eval expressions in one search using a comma to separate subsequent expressions. The eval command evaluates mathematical, string, and boolean expressions. exists) and also helping you identify potential patterns and trends between different fields. I'll be able to tell if these servers are working properly by extracting certain strings (specified in the rex statements) and checking if they are zero or not. Regarding returning a blank value: When you use count, it will always return an integer, you may have to use another eval to set the field to blank if it is '0'. If the field name that you specify matches a field name that already exists in the search results, the results of the eval expression overwrite the values in that field. Eval and its importance sourcetypeaccess eval. I am working on monitoring a load balancer by checking how many logs are generated on each of my servers.
