:: ERROR :: Cannot parse smokeping config file.

[soymgomez]

Hello @deajan ,

I am testing your project to use it together with our Smokeping.

When using the function to import Targets from Smokeping I always get this error:

2022-04-27 17:14:37,910 :: ERROR :: Cannot parse smokeping config file. We need as much titles as host entries.

my configuration line is as follows:

[SMOKEPING_SOURCE]
# Optional path to smokeping config file where hosts will be read
smokeping_config_path = /etc/smokeping/config.d/Targets

Can it be because of using @includes in our Targets file? My Targets file looks like this:

*** Targets ***

probe = FPing

menu = Top
title = Network Latency Grapher
remark = Welcome to the SmokePing website of <b>Insert Company Name Here</b>. \
         Here you will learn all about the latency of our network.

# 1. Group1
@include /etc/smokeping/config.d/group1.conf

# 2. Group2
@include /etc/smokeping/config.d/group2.conf

# 3. Group3
@include /etc/smokeping/config.d/group3.conf

...

Thank you very much

[deajan]

Indeed, I did a very basic implementation of smokeping target reading. I could add it quite quickly if you can send me a couple of example group files perhaps.

[soymgomez]

What we do is to split the Targets file into chunks.

Here is an example of the files from one of Smokeping's servers:

• /etc/smokeping/config.d/Targets

*** Targets ***

probe = FPing

menu = Top
title = Network Latency Grapher
remark = Welcome to the SmokePing website of <b>Insert Company Name Here</b>. \
         Here you will learn all about the latency of our network.

Mind if I use those as files for tests (published on this git ?)

[soymgomez]

No problem, they are all public hosts! ;)

[deajan]

I pushed a proper smokeping config reader with tests, which passes the tests including the files you posted.

Be aware that I also moved everything into a traceroute_history subdirectory in order to make the directory scheme pip compatible, so you'll probably need to reconfigure paths if you are using git pull.

[deajan]

You should also pip install -r requirements.txt since I removed inplace requirements in favor of packages.

[soymgomez]

I'll try it out this afternoon/evening! Thank you very much

I downloaded the latest commit and tried to do a init-db but I'm getting the following error:

# ./traceroute_history_runner.py --config=traceroute_history.conf --init-db
Traceback (most recent call last):
  File "./traceroute_history_runner.py", line 32, in <module>
    from traceroute_history import config_management, trparse, schemas, models, crud
ModuleNotFoundError: No module named 'traceroute_history'

[deajan]

I needed to change the paths for it to become a pip package later. Until now, the easiest way for you to run it is to declare the path to the package, eg with the new path handing you would have:

/somepath/traceroute_history/traceroute_history/traceroute_history_runner.py

You would start to declare the path to the package before running with:

export PYTHONPATH=$PYTHONPATH:/somepath/traceroute_history

Then you can run like always

python3 /somepath/traceroute_history/traceroute_history/traceroute_history_runner.py [options]

[soymgomez]

I was testing it now on one of my servers and I got this error:

In case it helps, I paste here my entire configuration file. The configuration is all default except for the Smokeping configuration, the path to the SQLlite file and the example Targets are commented out.

[...]

Sorry, no difference:

# export PYTHONPATH=$PYTHONPATH:/opt/traceroute_history
# python3 /opt/traceroute_history/traceroute_history_runner.py --config=traceroute_history.conf --init-db
Traceback (most recent call last):

My traceroute_history.conf is pretty much identical to @soymgomez 's with the only difference being the smokeping_config_path line where I don't have a path, but a single file to parse:

[SMOKEPING_SOURCE]
# Optional path to smokeping config file where hosts will be read
smokeping_config_path =/opt/smokeping/etc/config

[deajan]

Sorry, no difference:

# export PYTHONPATH=$PYTHONPATH:/opt/traceroute_history
# python3 /opt/traceroute_history/traceroute_history_runner.py --config=traceroute_history.conf --init-db

@georgetasioulis Please have a look at the path I stated. In your case, you would have export PYTHONPATH=$PYTHONPATH:/opt since you don't have a traceroute_history package subdirectory in the traceroute_history git directory.

[deajan]

@soymgomez Thanks for sharing your config file, makes things easier. I've pushed commit https://github.com/deajan/traceroute_history/commit/795ec575f2bea5f47415b19a2968bd7053a49b19 that fixes the targets from smokeping to look like those from normal config file. Can you give it a spin perhaps ?

[soymgomez]

@deajan I just tested it on my test server and it works fine.

I'm going to try to fix the integration with Nginx as I have to add the Path to avoid the error:

2022/05/06 16:01:09 [error] 1192589#1192589: *1 FastCGI sent in stderr: "Traceback (most recent call last):
  File "/usr/lib/cgi-bin/smokeping_th_helper.fcgi", line 22, in <module>
    from traceroute_history import traceroute_history_runner
ModuleNotFoundError: No module named 'traceroute_history'" while reading response header from upstream, client: xx.xx.xx.xx, server: smokeping.xxxxxxx.net, request: "GET /smokeping/smokeping_th_helper.fcgi?target=ANYCAST.AS60068 HTTP/2.0", upstream: "fastcgi://unix:/var/run/fcgiwrap.socket:", host: "smokeping.xxxxxxx.net"

[deajan]

Since you moved smokeping_th_helper.fgci from traceroute_history directory to /usr/lib/cgi-bin, you have to add that path as env for nginx, or directly into the script. In the fcgi script you could add the following

sys.path.append('/opt/traceroute_history')

Of course, using fastcgi_param PYTHONPATH /opt/traceroute_history seems an easier idea to me.
