unstable work of graph

[Nello-Angelo]

unstable work of graph sometimes graphs are vanishing and can`t make full node graph. I use service mesh linkerd

[Nello-Angelo]

also there is no distinct separation of topologies by namespaces. The current topology is terrible and awkward to use

[def]

@Nello-Angelo, could you please check the Prometheus (VictoriaMetrics) scrape interval for the coroot-node-agent targets, as well as the refresh interval configured in Coroot (Settings -> Prometheus)?
Coroot requires that the refresh interval is not set to a value lower than the scrape interval.

[Nello-Angelo]

scrape_interval: 15s
Refresh interval: 15s

[def]

What problem is Coroot showing on the Instances tab?

It seems that the node-agent is not installed on all nodes in the cluster

[Nello-Angelo]

in the cluster 12 nodes
