Its functionality has been replaced and superseded by the Distributed Management Console, a feature that is included with Splunk Enterprise as of version 6.2. We recommend that you migrate from S.o.S to the DMC for all your Splunk monitoring and introspection needs at your earliest convenience.
Please consult Splunk Answers to learn about best practices to deploy the S.o.S app in a distributed environment.
1) If Sideview Utils version 1.1.7 (or later) is not installed, please install or update it before installing S.o.S.
2) Install the S.o.S app:
If you have a distributed search environment, make sure you install S.o.S on the search-head(s) only. From the search-head the app can discover search-peers present in the distributed deployment.
3) Download and install the Splunk on Splunk add-on (S.o.S TA) on search peers to provide resource usage information to S.o.S.
This add-on provides data inputs that gather memory and CPU usage for Splunk Web, splunkd, and search processes as well as other system resource information. For more information, see the README file available with the S.o.S TAs.
Note: You do not need to install the S.o.S add-on on a Splunk instance were the S.o.S app is already installed. The S.o.S app ships with the same data inputs.
[SOS-11] Fixed an issue where ps_sos.ps1 would log many "WriteError" exceptions to splunkd.log and insert incorrect values in its events.
[SOS-12] Fixed an issue where the "Security Health Check" view would fail to show results on a Splunk Enterprise 6.2 instance.
[SOS-19] Retired the "Bucket information" panel in the "Cluster Master View" as it was dispatching potentially unsafe rest-based searches against the Cluster Master's buckets endpoint.
[SOS-39] The securityinfo.py search command - and by extension, the "Security Health Check" view - now appropriately scopes its results to the instance picked by the user.
[SOS-40] Fixed an issue where the "cluster" command would fail to show event cluster counts due to a change in internal behavior.
[SOS-113][SOS-117][SOS-141] Forwarder instances will no longer be listed in the "Host" pulldown of the "Search Usage Patterns, "Scheduler Activity" and "Search Activity" views.
Full support for Splunk Enterprise 6.1
NEW VIEW: Search > Search Activity
Provides deep insight into instance-scoped search workload, expressed as search concurrency, resource usage or aggregate search time. These metrics can be grouped by various relevant search properties: mode (historical vs. real-time), type (ad hoc vs. scheduled), user...
NEW VIEW: Resource Usage > Indexes Disk Usage and Properties
Allows a deployment-wide or instance-scoped view of index disk usage and other properties. Can be scoped to one or all indexes.
NEW VIEW: Deployment Status > Warnings and Errors > Security Health Check
A series of checks against security settings in your Splunk Enterprise installation.
NEW VIEW: Indexing > Index Replication > Cluster Service Activity
Shows service activity in a Cluster in great detail, allowing to better understand maintenance and repair operations undertaken by the Cluster Master and its peers.
24 bugs fixed! See the RELEASE-NOTES file for full details.
New features for the Deployment Topology view
Data overlays for instance status and resource usage (CPU/Memory).
NEW VIEW - Search > Search-head Pooling Performance
Check the usage and performance of the NFS shared storage device central to search-head pooling deployments. Compare performance metrics both at the storage (NFS) and application (Splunk) levels.
NEW VIEW - Indexing > Metrics > License Usage - Today
Get a license usage report for the current day and a history of license warnings for the current license window. (Applies to Splunk 4.3.x and 5.x only)
NEW VIEW - Indexing > Metrics > License Usage - Last 30 Days
Get a daily license usage report for the past 30 days and break it down by pool, indexer, source, sourcetype or host. (Applies to Splunk 4.3.x and 5.x only)
NEW VIEW - Indexing > Index Replication > Bucket Fix-up Activity
Monitor the status and progress of bucket fix-up operations in a cluster.
10 bugs fixed! See the README file for full details.
[SUP-723] Fixed an issue where scheduled searches "sos_splunk_instances_info" and "sos_refresh_splunk_servers_cache" would run several times per minute instead of at their scheduled time on a pooled search-head running Splunk 5.0.3. Note that the root cause of this problem is core Splunk bug SPL-68970.
