Unable to monitor node with RTview

[tom_w]

Hi,

I have a single node running on my local computer. I am trying to get RTview up and running with no success.

The node appears to be running ok:

cardano@tom-ThinkPad-X220:~/cardano-node$ cardano-cli query tip --mainnet
    {
"blockNo": 2637139,
"headerHash": "e0ba3286ec9e95806c32886c7065205fe941a421ed004f81337e635393f03a56",
"slotNo": 2638653

}

Here is the config file which hopefully I have modified correctly, according to guidance from RTview:

Here is RTview webpage, any idea why data is not getting to the webpage?

[Alexd1985]

Hello,

if you keep the default port 8024 , the web-page will be available on http://127.0.0.1:8024

And at the end… again they specified:

After you pressed Enter , RTView will be launched, and you can open http://127.0.0.1:8024 (if you chose default web-port) and see the web-page.

Then, why are u using 0.0.0.0:8024 to access the node?
Cheers,

[tom_w]

Hi Alex,

Yeah, sorry, I should have said I tried 0.0.0.0:8024 after having no luck on 127.0.0.1:8024

I’ll go through the config file again to make sure there are no errors there. Any other ideas?

Thanks

[Alexd1985]

ur server is running on the same machine , I mean on your desktop? or it has a public IP address… hosted separately?

try with public_IP:8024

also u can check this post

Force RtView to listen on public IP?

Does anybody know how to force RtView to listen on the public IP of the machine for HTTP-traffic instead of 127.0.0.1!? (referring to port 8024) One can force proper opening of the sockets for the ports receiving the trace data using the rt-view.yaml configuration file. Like this: - remoteAddr: tag: RemoteSocket contents: - XX.XXX.XXX.XX - '3100' nodeName: nice-node-name By default XX.XXX.XXX.XX is 0.0.0.0 and I run into the same problem here - but forcing listening the publ…

[tom_w]

Yes server was running on same machine, my laptop. Haven’t had time to look at again so still no solution, will get back to it eventually. Thanks for your help

Hi Tom I am having the same issue. I can’t properly install RTView…the instructions are pretty unclear on Github…I am not sure what to do from here, but at least my node is running!

[tom_w]

Yeah, I still have had no luck with RTView. I reinstalled the node using this guide:

https://cardano-community.github.io/guild-operators/#/Build/rest

and then ran the gLiveView script located in

relay@vmi524346:/opt/cardano/cnode/scripts$ ls
balance.sh          cnode.sh         cntools.sh            env            logMonitor.sh      setup_mon.sh    system-info.sh
cabal-build-all.sh  cntools.config   createAddr.sh         gLiveView.sh   rotatePoolKeys.sh  sLiveView.sh    topologyUpdater.sh
cncli.sh            cntools.library  deploy-as-systemd.sh  itnRewards.sh  sendADA.sh         stack-build.sh

to give some basic monitoring:

I had the same issue and solved it by adding “TraceForwarderBK” to

“defaultBackends”: [
“KatipBK”,
“TraceForwarderBK”
],

in the node’s config file.
However, I didn’T find any documentation about it

[billcarroll]

This worked for me as well

When configuring RTView on run, the instructions say to Find options → mapBackends in config.json for the node and redirect required metrics to “TraceForwarderBK”

I added “KatipBK” to the node config and that seems to be working. Is “TraceForwarderBK” incorrect?
