I am okay wit the example data set from audioscrobbler, which is totals in 75K users and 50K items. But mine is to tiny ,since I am in the start of the road. So will be happy to know what are the minimum data set used in Myrrix. The reason of asking that is a warning:

thank you for everybody who can assist
I was able to ingest a file with 10 lines of associations only.
By the way, Myrrix is migrating to Oryx now, you may ask Sean Owen on https://groups.google.com/a/cloudera.org/forum/#!forum/oryx-user

Microsoft secure score API provides score for Office 365 configurations. It provides list of best practices to secure O365 account. If we fix the mentioned issue and when we retrieve the secure score results again, we are getting same old result. As per Microsoft documentation, secure score should be updated daily but it is not happening. Any idea about its refresh frequency?
https://learn.microsoft.com/en-us/graph/api/resources/securescores
The official document explains it like this:
The score is calculated once per day (around 1:00 AM PST). If you
make a change to a measured action, the score will automatically
update the next day. It takes up to 48 hours for a change to be
reflected in your score.
According to the documentation, the score should be calculated once a day, starting at about 1:00 AM Pacific time, but it will take several hours to run. There are also instances where the job fails and we need to restart it so this might be why you don't see it updated at the exact same time every day.
Moreover, it may take up to 48 hours to refresh, so I suggest you wait until 48 hours to see if it refreshes.
Our #flurry App Data Download appears bugged.
We requested raw data for analytics recently Oct, 2rd 2020, but the result was not enough than our expected data amount. there are only a few raw data. for example we compered Arbitrary period old which got around Sept 11th to new which got after 5th Oct.
around Sept 11th data is 16MB
after Oct 5th data is 18.6kB
Above data is same period and same data choice.
There is few raw data which is reported but also there is enough event counts on the Flurry Analytics. the every data graph is normal.
Flurry analytics web site. --> about 30,000 data
Exported data --> about 60 data
It's not relate the export file format (CSV, XML, JSON).
It's same result
Add information 2020.Oct.7th
I did data download how to this below.
Flurry analytics console login
Click the Data Download of Sessions
And select application SmartSync(iOS) or SmartSync(Android)
Set Event for any period, and CSV or else.
Is this a known issue or recent bug?
If someone know the any tips or correct setting, could you please advice?
This is now fixed. Please email support if you have further difficulties.
We have apprx 2 million distributed data objects(not replicated) in cache of 10 nodes cluster (apprx 500 MB data). Backup count is one. We are seeing given below errors/warnings.
Do you guys know when I can see these errors? I have sanitize some logs to not share something sensitive. Majority of time we do cache read(around 400 request/second), and whole cache gets reinitialized every 2 hours.
I know that we can do replicated cache to improve performance, but wondering what's wrong going on here. When I run with smaller cluster(e.g. 5 nodes) then everything works fine.

Why do you have such huge number of input and output threads (30/50). In most cases the default of 3+3 is more than sufficient. If you don't have 50+ connections; all these threads will be idle. Even with 50+ connections, you will not get good performance with so many IO threads.
The error you are seeing seems to indicate a networking issue: response can't be send. The big question is why this is happening.
Can you enable diagnostics:
http://docs.hazelcast.org/docs/latest-development/manual/html/Management/Diagnostics/Enabling_Diagnostics_Logging.html
And send the log files to peter at hazelcast dot com So I can have a look at it.
I have a questions about Visual Studio 2013. We're running load tests with agents. In total, we have 5 agents and 1 controller. In the agent properties (from the Manage Test Controller option), I have set the weighting to 15 for each agent. This totals 75 - so does that mean that the controller handles the rest?
The documentation is a little vague as it suggests that if you make one 20 (e.g. A) and another 40 (e.g. B) that B will run double the load of A. However I am not sure how this works when we have 5 agents set to 15?
Thanks in advance!
The weights are just specifying ratios. If all the values are the same (ie 15 in your example) then each agent will get the same load.
Suppose you want to run a test with 300 simulated users with your 5 agents each having a weight of 15. Then each agent gets approximately (300*15)/(5*15) users, ie 60. The "approximately" is added because other values may not divide nicely with integers.
Suppose instead that the 5 agents have weights of 7, 11, 13, 17 and 19. Then the 300 simulated users will be spread as approximately 31, 49, 58, 76 and 86, respectively.
See here and here for more details.
I noticed myrrix creates a file within a tmp directory that is like a model.
Can I start myrrix with this information in order to save time and not have to re-ingest the data.

Yes, you can. You just put a model.bin.gz in the local directory that it's running over. That could be a model you saved separately. You could also create one manually, although that would require some hacking on the code to serialize your own model.
