If you are resource constrained, you can use workload management to put these searches in a high priority pool to get them more resources so they complete faster.Or, try to reduce the search execution time:.Change the schedule frequency so it is higher than execution time for the search.To fix this problem, you need to identify which scheduled searches are skipped due to this reason and then do one of the following: For instance, if a job takes 10 minutes to complete and runs at a 5 minute frequency, then it will skip. If a scheduled search job cannot be completed before the next period starts, it will be skipped. This limit is defined by in the Splunk Enterprise nf file and generally, you don’t need to change this attribute to more than 1 (default). every 5 minutes) and by default only 1 instance of a scheduled search can run at any given time. Scheduled searches run at a certain frequency (e.g. The maximum number of concurrent running jobs for a historical scheduled search has been reached Maximum auto-summarization searches = x max concurrent scheduled searchesĪs well as being aware of these calculations, you can use ad hoc search quota control (in Enterprise and Cloud) to limit ad-hoc searches so they do not take away all search slots.Maximum concurrent scheduled searches = x total max concurrency.Total maximum concurrency = x number of CPU cores in SH/SHC +.Some of these calculations are shown below for a single search head, but the principal can be applied to a search head cluster as well: This means that ad-hoc searches can use up to the maximum amount of search slots, essentially leaving none for scheduled searches. There is a default limit of the search slots that scheduled searches can use, but there is no default limit on ad-hoc searches. Both scheduled searches and ad-hoc searches use these search slots. This is done to protect the system from slowing and stopping if the search workload is much higher than resources available.īy default, the system total maximum concurrency (maximum search slots) is calculated based on the number of CPU cores on a search head (SH) or across a search head cluster (SHC). In this case, the alert sends an email notification when it triggers.Splunk restricts the number of concurrent searches running on the system, which you can think of as search slots. The following example shows the stanza for a saved search with its alert action settings. nf contains a stanza for each saved search.
Open or create a local nf file at $SPLUNK_HOME/etc/system/local.įor apps, open or create the nf file in the application directory: $SPLUNK_HOME/etc/apps//local Example nf stanzaĪlerts use a saved search to look for events.

Review the steps in How to edit a configuration file in the Splunk Enterprise Admin Manual.Only users with file system access, such as system administrators, can configure alerts using configuration files.Splunk Enterprise To configure alerts using the configuration files, follow these steps. You can't configure alerts using the configuration files. Splunk Cloud Platform Use the Splunk Web steps to configure alerts. For reference, see nf in the Splunk Enterprise Admin Manual. If you have Splunk Enterprise, you can configure alerts by editing nf. You can use Splunk Web to configure most alerts.
