# Help Center Spider
## About
This is a spider tool with which you can visit all links on https://docs.otc.t-systems.com to find urls that are not correct.
## Requirements
After you cloned the repository you need to prepare an environment to run the tool. You can easily do this with
python virtual environment:
The Open Telekom Cloud Helpcenter Spider is a spider tool visiting all
links starting from its landing page on https://docs.otc.t-systems.com/
to find and identify urls that are not correct. It parses all types of
hyperlinks and normalizes them into a canonical format. The spider
descents into the document tree via [...] bredth or width first search.
[and does what?] [when is logged which event?]
## Getting started
Once you installed the code and its required packages into an virtual
environment and checked its configuration file `config.json`, the web
spider starts invoking the tool without any arguments. Results are
listed in [... TBD].
## Requirements and Installation
After you cloned this repository you need to prepare an environment to
run the tool. You can easily do this with a Python virtual environment:
```
$ cd <local_folder>/
$ cd _local_folder_/
$ git clone https://gitea.eco.tsi-dev.otc-service.com/infra/hc-spider.git
$ cd hc-spider
$ python -m venv venv/
$ source venv/bin/activate
(venv)$ python -m pip install -r requirements.txt
```
## Configuration
In _config.json_ you can define a couple items:
In _config.json_ you can define several items:
- _watchdog_file_: if you run the tool in the background and want to stop it properly (not using `kill`),
just send an exit message into the watchdog file: `echo exit > watchdog.fifo`
- _timer_runtime_: maximum runtime limit in seconds
- _log_dir_: logging folder
- _logging_interval_: frequency of dumping log files
- _workers_: number of workers (background processes) you want to run. If you set to 0 it will count from the number of cores (_number_of_cores_ - 1)
- _watchdog_file_: if you run the tool in the background and want to
stop it properly (without sending a signal with `kill`), just send
an exit message into the watchdog file: `echo exit > watchdog.fifo`.
- _timer_runtime_: maximum runtime limit in seconds.
- _log_dir_: logging folder.
- _logging_interval_: frequency of dumping log files.
- _workers_: number of workers (background processes) you want to run.
If you set to 0 it will count from the number of cores
(_number_of_cores_ - 1)
- _starting_point_: base url where to start
## How to run
There are two ways to do it
## Operations
There are two ways to start the spider:
### In foreground
### In the foreground
```
$ source venv/bin/activate
$ python main.py
(venv)$ python main.py
```
### In background
### In the background
```
$ source venv/bin/activate
$ nohup python main.py > log/hc_spider.log 2> log/hc_spider.err <&- &
(venv)$ nohup python main.py > log/hc_spider.log 2> log/hc_spider.err <&- &
```
In case you running the tool in background you can stop the execution with `$ echo exit > <watchdog_file>`
### Stopping the process polietely
To stop the tool when run in the background, send a command to the
control fifo with: `(venv)$ echo exit > _watchdog_file_`
