logstash issues

[eallen-vaskywire]

no matter what I do I keep getting logstash Stopped with exit code 123, everything else seems to be working, I can see OSPF data however, the hostname import does not seem to remain after refresh or log out.

I am not sure what I am doing wrong with this. I have included the logs from logstash, any help with this would be greatly appreciated.

Hi @eallen-vaskywire ,
since it's a logstash issue I suppose that you are using OSPF Watcher, right? could you please share your logstash version? Uh, I see, version is 7.17.0

[eallen-vaskywire]

yes for OSPF Watcher, sorry if I put this in the wrong thread/project. Logstash version is 7.17.0

[Vadims06]

I can suggest the following tests:
Start logstash container

[ospf-watcher]# docker run -it --rm --network=topolograph_backend --env-file=./.env -v ./logstash/pipeline:/usr/share/logstash/pipeline -v ./logstash/config:/usr/share/logstash/config logstash:7.17.0 /bin/bash

Inside container run this command:

bin/logstash -e 'input { stdin { } } filter { dissect { mapping => { "message" => "%{watcher_time},%{watcher_name},%{event_name},%{event_object},%{event_status},old_cost:%{old_cost},new_cost:%{new_cost},%{event_detected_by},%{subnet_type},%{shared_subnet_remote_neighbors_ids},%{graph_time}" }} mutate { update => { "[@metadata][mongo_collection_name]" => "adj_change" }} } output { stdout { codec  => rubydebug {metadata => true}} }'

It will expect an input from CLI, so copy and past this line of log

2023-01-01T00:00:00Z,demo-watcher,metric,10.1.14.0/24,changed,old_cost:10,new_cost:123,10.1.1.4,stub,10.1.1.4,01Jan2023_00h00m00s_7_hosts

The output should be:

[INFO ] 2024-05-13 21:15:25.462 [[main]-pipeline-manager] javapipeline - Pipeline started {"pipeline.id"=>"main"}
The stdin plugin is now waiting for input:

Try changing the Logstash version in the .env file to LOGSTASH_OSS_VERSION=7.17.21

I ran into the same issue and this resolved that error. I don't think it's a result of it, but that followed up with errors about Logstash being unable to reach Elasticsearch. The lines are still commented out in .env, but I'm still working on this to see if I can resolve it along with a few other issues.

[Vadims06]

Hi @eallen-vaskywire
was using of 7.17.21 version helpful for you?

[eallen-vaskywire]

YES! Thank you so very much!!! I think we have finally got OSPFwatcher working, however for some reason it quits getting OSPF data after several hours and the only way we have found to get it working again is to reboot the stack.

There are a few bits that we are still trying to sort through like

1. getting the right syntaxes and such for ELK (if you have some examples for this that would be amazing),
2. Netbox integration for hostname population and resolution we currently use phpipam/powerdns not Netbox however I did find a plugin to sync PowerDNS-->Netbox and we are testing that out.

[Vadims06]

Thank you @vrelk-net for your advise and @eallen-vaskywire for confirming - I will set 7.17.21 as a default version.
I will be more than happy to help you make OSPF Watcher stable. Feel free to ask questions here or via admin at topolograph.com. Your feedback is extremely valuable.
According your questions:

1. getting the right syntaxes and such for ELK is it fair to say that you are talking about a set of commands, which let to check that OSPF Watcher is healthy and help with troubleshooting? I have troubleshooting section in OSPFWatcher repo, but basically the first command is to get logs of failed container using docker logs watcher (could you please share logs of failed container?), if a container works - check that quagga/frr debug OSPF (check a command under troubleshooting section#1), etc. Probably I can provide more commands based on your inputs.
2. I decided to deprecate Netbox support inside topolograph and expand such option via API. Netbox is developing quite fast and I can't keep up with changes :) So I can suggest export hostnames from your system and import them via CSV.

[vrelk-net]

@Vadims06 would it be possible for me to get access to the project that has the actual source for Topolograph? I'm hoping I might be able to work on a few things. One of which being the user system. (I sent an email last week, but haven't heard back. Figured I'd just add it here instead of creating an issue to request it.)

[Vadims06]

@vrelk-net , could you please elaborate on the user system a little bit more? Did you send an email to admin at topolograph? Sorry, I haven't received it. Yeah, I keep topolograph source code closed, because whoever contacted me to onboard new vendor into Topolograph and shared their LSDP for this - I keep LSDB output for my unit tests as is. I didn't anonymous it, but with restricted access. All in all, I will be glad to get your feedback and listen to your ideas.

[Vadims06]

can we close this issue?..
