# Job Visualizer
|
||||
This project is meant to visualize scheduled jobs for a given timespan,
|
||||
so you're able to see bottlenecks or timeframes where to many jobs are run simultaneously.
|
||||
|
||||
**This tool analyzes a CSV file and creates an HTML file.**
|
||||
|
||||
## Usage
|
||||
For usage information call
|
||||
```
|
||||
./job-visualizer -h
|
||||
```
|
||||
|
||||
That will result in
|
||||
```
|
||||
Usage of ./job-visualizer:
|
||||
-file string
|
||||
File to import
|
||||
-output string
|
||||
File to generate
|
||||
```
|
||||
|
||||
* `--file` Is a csv file you want to analyze
|
||||
* `--output` Is an html file the tool will generate
|
||||
|
||||
### CSV File Format
|
||||
Currently the format is fixed and planned to be configurable in the future.
|
||||
|
||||
You need the following columns:
|
||||
* Prefix/Group
|
||||
* job_name: The name of the job
|
||||
* job_type: The type of the job
|
||||
* start_time: A string with start times for the group, e.g. `"2019-11-02 21:10:21,2019-11-03 21:19:33"`
|
||||
* end_time: As start_time, but the end times, e.g. `"2019-11-02 21:10:22,2019-11-03 21:19:33"`
