version to REST/json statistics reporting
|
|
|
|
|
|
This patch adds extended status reporting with the url
http://server:port/simstatusx/ [^] . The data is returned
in json format as "text/plain" type.
|
|
these are now inaccurate
* Correct count of assets in cache
|
|
|
|
* Adds a prototype web stats module which is disabled by default. It's functional with one report right now, however, the database structure may change, so I don't recommend enabling this to keep actual stats right now. I'll let you know when it's safe.
* Adds Prototype for ajaxy web content
* removed a warning or two.
|
|
* I believe this was the cause of the remaining packet_out_of_order messages in the Linden client logs
* There were race conditions where multiple clientstacks would overwrite each other's sequence numbers
|
|
primtive at the moment - only the last time is kept for some classes of request
* This can be seen as "Latest asset request time after cache miss" in show stats on the region console
|
|
* This is a HUGE OMG update and will definitely have unknown side effects.. so this is really only for the strong hearted at this point. Regular people should let the dust settle.
* This has been tested to work with most basic functions. However.. make sure you back up 'everything' before using this. It's that big!
* Essentially we're back at square 1 in the testing phase.. so lets identify things that broke.
|
|
|
|
* Potentially useful for diagnostics without needing to log in a client
* Packet queue statistics commented out for now pending a better way to cope with the information overload
|
|
* commented out [Obsolete(....)] attributes where no replacement feature
was available: if we want to attribute code that we think needs to be
reworked, we should define a new attribute and use that instead
(together with a little tool to retrieve all the attributed code then)
* commenting out unused variables
|
|
something else
|
|
* This includes problems such as connection failures and timeouts. It does not include 'asset not found' replies from the asset service.
|
|
places in show stats
* trade easier readability for pointless accuracy
|
|
clear-assets command is used on the region console
* stop waiting for garbage collection when GC total memory used is requested, in case the periodic request of this lags the sim
|
|
some idea of how these evolve
* When returning GC.GetTotalMemory(), force collection first in order to get more accurate figures
|
|
|
|
* This is the GC.GetTotalMemory() method, which I'm guessing does not include memory used by the VM (hence the memory usage reported in top on linux would be much higher)
|
|
|
|
|
|
|
|
repetitive client requests for the same missing texture
* This is to maintain some visibility on the problem, since I removed the intentionally irritating log messages for this
|
|
the region server
* In theory, this should be a somewhat useless statistic since the user server will already have tried to use the inventory service to retrieve the avatar's skeleton. If this
fails, login is halted completely.
* Nonetheless I'm recording it anyway just to see whether it happens (yes, I'm too lazy to scan the logs...)
|
|
* If extra stats not sent to the viewer are available on an opensim server, they are now uniformly accessible using the 'show stats' command
|
|
Collectors - this seems more intuitive
|
|
(this took a while to run).
|
|
|
|
|
|
|
|
* Correct asset cache stats table heading
* Correct spelling mistake in AssetCache (thanks ChrisD!)
|
|
|
|
* This will show the packets waiting in each queue for each client logged into a region server
* These are displayed using 'show stats' on the region command line
* This is in pursuit of a memory leak.
* This will require a prebuild
|
|
If no scriptengine is specified then don't try to load any.
|
|
|
|
* You can type 'stats' at the REGION# prompt to get this information in grid or standalone mode
* Don't take these numbers as gospel yet, since for some reason textures displayed from inventory which require downloading from the server are being recorded as assets
rather than textures
* But I don't have any reason to believe they aren't broadly accurate.
* I've put these in so I can tell whether the high memory usage on regions is down to the asset/texture cache
* This will require a prebuild
* DEV: Only adds needed to be implemented since, as far as I can tell, assets cached are currently never released. For my part, seeing large cache memory numbers will
provoke me to think about doing something about this.
* DEV: Now switched to using a singleton to get the stats reporters rather than threading the object through various layers
* DEV: Will refactor the other server stats reporters to do this in one of the next commits
|
|
|
|
|
|
* Passing the stats collector through object chains is not ideal - this will change when more stats come in
* This change will need a prebuild
|
|
* The hooks are still plugged in too high at the asset server, but then next layer down is the database and this may be refactored soon.
* This change will requires a prebuild
|
|
|
|
* Typing 'stats' on the command line will given total number of successful logins today and yesterday
* A little bit more to come, probably
* Refactoring will follow next
