[Web Console] Does Ignite Web Console Docker Image contains monitoring page

Hi Support, In console.gridgain.com, there is a monitoring page showing the many metrics for the cluster. But I deploy the Web Console Docker Image (standalone) and it does not show the monitoring page. Please advise how to enable the monitoring page. Thank you. James Wang / edvance Mobile/W

C++ computer delay

Hi igniters, I've a problem when I launch a sequence of about 350 compute funcions in my cluster of 10 node. I register a delay in the first launcher od about 10 sec. after that, it works smoothly. If I launch the same numbers of task on a single node, there 's no delay. It seems like a problem in

Re: Distributed Training in tensorflow

Hi, Ignite ML natively has a multilayer perceptron (see https://apacheignite.readme.io/docs/multilayer-perceptron), so you can use it to build a simple neural network. But, if we are talking about deep learning the answer will "no", Ignite ML provides it only via integration with TensorFlow. -

Re: How to define customized NodeID8

Hello! This is not cluster name, it is instance name, I can see how it could be displayed in place of NodeID8 but not as cluster name. There's *IGNITE_CLUSTER_NAME* system property to set cluster name, but I'm not sure if it is supported by Web Console. Regards, -- Ilya Kasnacheev ср, 20 февр

Re: External multiple config files for Docker installation

A lower-lift method might be to put your config files in the local file system and create a volume to make it accessible from your container. Something like: docker run —rm -it -v /home/me/config:/opt/ignite/config -e CONFIG_URI=file:///opt/ignite/config/local.xml apacheignite/ignite:2.7.0 R

Re: External multiple config files for Docker installation

Ignite's Docker image doesn't have a parameter for that. You can create your own Dockerfile extending Ignite's image and define and handle a new parameter there. Stan kyro wrote > Hi akurbanov, > > Yes, I have the lines as you mentioned in my config. I was asking as to > how > do I pass the two

Re: Index inline size

Depends on the use case. Sometimes you want to save the memory as much as possible, and then you would use a lower inline size. However, in most cases you actually need a higher value because that will greatly improve the performance. Starting 2.7 there are warnings with a recommended size (calcul
