[jira] [Commented] (FELIX-4141) Provide a full Web Console plugin
for thread dumps
[ https://issues.apache.org/jira/browse/FELIX-4141?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13771638#comment-13771638 ]
Henry Saginor commented on FELIX-4141:
--------------------------------------
Attached is initial version Web Console plugin.
So, far the following is implemented:
* create repeated thread dumps at specified interval
* store thread dumps in files (repeated set is stored in each file)
* make thread dumps accessible as plain files or zips
* remove thread dumps from the store
* Include the thread dump files as attachement when creating the "Inventory Printer full ZIP"
If someone can review and provide feedback maybe I can start working in the following.
* Add automatic deadlock detection: Probably by regularly checking for the existing deadlocks and then requesting a thread dump.
* Deadlock detection in the Plugin: If the plugin is opened and a deadlock is detected a clearly visible warning/information is shown.

> Analogous to the Memory Usage plugin a Web Console plugin for the thread dumper would be helpfull:
> * to automatically create repeated thread dumps
> * store thread dumps in files
> * make thread dumps accessible as plain files or zips
> * make thread dumps accessible as plain or zipp-ed files containing all dumps in a single file
> * remove thread dumps from the store
> * Include the thread dump files as attachement when creating the "Inventory Printer full ZIP"
> * Add automatic deadlock detection: Probably by regularly checking for the existing deadlocks and then requesting a thread dump.
> * Deadlock detection in the Plugin: If the plugin is opened and a deadlock is detected a clearly visible warning/information is shown.
