Sample of file data sent from buckets to nodes This graphs sums the data transferred from bucket storage to individual nodes. Based on uploaded-files mirrored from bucket storage to nodes, excluding data mirrored between nodes. There are too many nodes to show them all. Instead this is meant to give a general indication of how well the file transfer is distributed among nodes.

Sample of file data sent between node pairs This graph sums the data transferred between specific node pairs. Based on uploaded-files that are mirrored between nodes, excluding data mirrored from bucket storage. There are too many node pairs to show them all.

HotSpot Crashes This widget looks for fatal exits of the JVM, as these can indicate the HotSpot compiler crashed. This is fairly rare, but can at times happen when the LogScale regex engine hits a bug in the JVM -- but other causes are also possible. This graph should almost always be empty, and if it shows many incidents grouped close together, it is likely related to a bug in the JVM. PLEASE NOTE that this widget only shows relevant data if stdout logs from the LogScale JVM instances are shipped to the repository being inspected.

Permissions
WidgetDescriptionType
Permission cache hit vs. miss For each request stemming from a user, all the permissions for this user is in some cases fetched. A cache exists to ensure that these permissions are not fetched multiple times. This time chart shows all permissions lookup vs. permission lookups resulting in a cache miss. The chart is divided into each level of permission. The purpose is to measure the value of the caches.
