If you are concerned about resource constraints, schedule any searches you save to run during off-peak times. ![]() In addition, the searches have been vetted by performance experts at Splunk to ensure they are as performant as possible. The searches included with the app are generally scheduled to run once a day, and leverage acceleration and efficient search techniques wherever possible. If you instead search domain controller logs with hundreds of thousands of users included, you would see additional load. For example, if you search Windows logs for two desktops, even the most intensive searches in this app add no discernible load to your indexers. If you save and enable searches included with the app in your environment, you could see changes in the performance of your Splunk deployment.Īs is true for all searches in Splunk, the amount of data that you search affects the search performance you see in your deployment. * Windows 10 - Firefox Performance Impact In addition to the above described scenarios, this app is periodically tested with the following client platforms: This app does not interfere or impact ES, and can be installed on an ES Search Head (or Search Head Cluster) safely. Because the app includes demo data, the app takes about 250MB of storage on the search head. Unless you save or enable searches included with the app, there is no increase in indexed data, searches or others. ![]() I have hunted and the only issue with SHC replication I’ve found was with a 54 GB KV Store, so you should feel very comfortable using SSE including this technique. ![]() The docs below detail that most SSE lookups using this technique would be a few MB in size, and it’s difficult to conceive of a lookup more than 1 GB. This wouldn’t be used by default, and even when used would be safe for virtually all scenarios as Search Head Clustering has a robust replication mechanism that works well for larger files. SSE installs into a SHC like any other SHC app, the only area where there is some minimal risk in a SHC setup is when using the Lookup Cache acceleration technique under the First Time Seen detection with very large lookups (See First Time Seen Detection -> Considerations for implementing the large scale version in this doc). The app includes many lookups with demo data that shouldn’t be replicated to the indexers, but also includes a nf file to prevent that replication, so that you needn’t worry. This app is safe to install in large size clusters, as it will not have an impact on indexers (unless you choose to enable many searches). If that happens to you, use a different browser to download the app file. Note: If you download the app as a tgz file, Google Chrome could automatically decompress it as a tar file.
