How to hide chart for web_log requests_by_vhost (too much data)

Help

Using the go.d collector of netdata v1.35.0-84-nightly I configured several jobs on a node:

jobs:
  - name: nginx
    path: /var/log/nginx/access.log
    log_type: csv

  - name: default
    path: /var/log/nginx/access.default.log
    log_type: csv

  - name: internal
    path: /var/log/nginx/access.internal.log
    log_type: csv

The node will host a few hundred vhosts which makes the chart chunky and meaningless most of the time.

vhosts
vhosts2172Ă—537 205 KB

How does one generally disable the requests_by_vhost chart, and is it possible to disable it for specific named jobs?

I tried the following entries in /etc/netdata/netdata.conf and restarted netdata with systemctl but no effect:

[web_log.requests_by_vhost]
    enabled = no
[web_log_internal.requests_by_vhost]
    enabled = no

Without this graph I think my browser will be much faster rendering the page! Thanks

Hi there, love the Mr Bean avatar!

The screenshot shows a chart named web_log_public.xxx and I don’t see that in the list.
You could just grab yourhost:19999/netdata.conf and see the charts that are already there with # enabled = yes

If this isn’t it, let us know so we can investigate further

Out of curiosity, how many vhosts do you have on this machine?

Thanks for replying

Oops I grabbed the chart from another server without explaining, just to demonstrate! The rest of the post should be accurate

You could just grab yourhost:19999/netdata.conf

When I check curl http://localhost:19999/netdata.conf I can see my failed attempt:

# section 'web_log.requests_by_vhost' is not used.
[web_log.requests_by_vhost]
	enabled = no

but no other mention of the web log collector

and see the charts that are already there with # enabled = yes

There’s not much mention of that actually, maybe I’ve gone wrong somewhere. The following blocks match:

[ml]
[health]
[plugin:proc:/proc/net/dev:eth0]

how many vhosts do you have on this machine?

The server has about 500 vhosts plus non-www redirects for a SaaS with “bring your own domain” feature. We do find other graphs useful like tracking 5xx responses

Apparently Remove per chart configuration. by vkalintiris · Pull Request #12728 · netdata/netdata · GitHub removed this capability. Investigating internally the reason.

We had performance issues with the specific configuration options. We’re getting someone to see about improving the collector.
