Uchiwa starts becoming slow with increased amount of clients

[ChrisOnToure]

We currently monitor around 9000 Clients with Sensu + Uchiwa in 5 different data centers.

When viewing all 9000 clients the dashboard becomes almost unusable slow. Is this a fact we need to accept or are there any tips how to improve Uchiwa performance with a large amount of servers.

Calling the Sensu server API directly is fast, so I believe it has something to do how Uchiwa gets the data and processes it.

Any suggestions are highly appreciated.

Your Environment

• Uchiwa version used: 0.25.2
• Sensu version used: 1.0.2
• Operating System and version (e.g. Ubuntu 14.04): CentOS7

We've just released Uchiwa 1.3.0 which adds concurrency to the Uchiwa backend process. This new version should perform significantly faster on large installations with multiple CPU cores to utilize.

Hi @ChrisOnToure @yakirgb @doublenns,

Will you please take a look and the new 1.3.0 release and let us know whether or not this addresses the latency you have been experiencing? Your feedback is much appreciated!

[ChrisOnToure]

Awesome news, thank you! Will plan the deployment and let you know then outcome.
btw where is the binary?

@ChrisOnToure Uchiwa 1.3.1 packages can be found in the apt & yum repositories: https://docs.uchiwa.io/getting-started/installation/

Hi sorry for late catch up. We deployed Uchiwa 1.5.0. The version feels snappier and overall faster. But still we reached 12k clients on 5 DCs and its far from being considered fast.
