# PDH - PagerDuty CLI for humans
[![Tag and build](https://github.com/mbovo/pdh/actions/workflows/build-release.yml/badge.svg)](https://github.com/mbovo/pdh/actions/workflows/build-release.yml) [![Nix](https://github.com/mbovo/pdh/actions/workflows/nix.yml/badge.svg)](https://github.com/mbovo/pdh/actions/workflows/nix.yml)
`PDH` is a new lightweight CLI for pagerduty interaction: uou can handle your incidents triage without leaving your terminal.
It also add some nice tricks to automate the incident triage and easy the on-call burden.See [docs](./docs) (TBD)
## Install
### Nix
If you are using [cachix](https://cachix.org) you can use the prebuilt packages:
```bash
cachix use pdh
``````bash
nix shell github:mbovo/pdh
```### Arch linux
```bash
yay -S pdh
```### With docker
```bash
docker run -ti -v ~/.config/pdh.yaml:/root/.config/pdh.yaml --rm pdh:0.3.10 inc ls
```### With pip
```bash
pip install pdh>=0.3.10
```### From source with nix and direnv
```bash
git clone https://github.com/mbovo/pdh
direnv allow pdh
cd pdh
pdh inc ls -e
```### From source with devbox
```bash
git clone https://github.com/mbovo/pdh
direnv allow pdh
cd pdh
pdh inc ls -e```
### From source
```bash
git clone https://github.com/mbovo/pdh
cd pdh
task setup
source .venv/bin/activate
pdh inc ls -e
```## Usage
First of all you need to configure `pdh` to talk with PagerDuty's APIs:
```bash
pdh config
```The wizard will prompt you for 3 settings:
- `apikey` is the API key, you can generate it from the user's profile page on pagerduty website
- `email` the email address of your pagerduty profile
- `uid` the userID of your account (you can read it from the browser address bar when clicking on "My Profile")Settings are persisted to `~/.config/pdh.yaml` in clear.
### Listing incidents
Assigned to self:
```bash
pdh inc ls
```Any other incident currently outstanding:
```bash
pdh inc ls -e
```### Sorting incident by field
```bash
pdh inc ls --sort assignee --reverse
```In case the field is not found the cli will notice you and print the list of available fields
```bash
pdh inc ls -e --sort unkn --reverse
Invalid sort field: unkn
Available fields: id, assignee, title, status, created_at, last_status_change_at, url
```You can always sort by multiple fields using comma as separator:
```bash
pdh inc ls --sort assignee,status
```### Auto ACK incoming incidents
Watch for new incidents every 10s and automatically set them to `Acknowledged`
```bash
pdh inc ls --watch --new --ack --timeout 10
```### List all HIGH priority incidents periodically
List incidents asssigned to all users every 5s
```bash
pdh inc ls --high --everything --watch --timeout 5
```### Resolve specific incidents
```bash
pdh inc resolve INCID0001 INCID0024 INCID0023
```### Resolve all incidents related to `Backups`
```bash
pdh inc ls --resolve --regexp ".*Backup.*"
```### Extract custom fields
You can also extract custom fields from the pagerduty json output:
You can nested fields using dot notation (i.e `service.summary`)
```bash
pdh inc ls -e --fields service.summary,status,title,assignee,created_at,url
```To understand the available fields you can get the raw json output and inspect it:
```bash
pdh inc ls -e -o raw
```## Rules
`PDH` support custom scripting applied to your incidents list. These `rules` are in fact any type of executable you can run on your machine.
```bash
pdh inc apply INCID001 -s /path/to/my/script.py -s /path/to/binary
```The `apply` subcommand will call the listed executable/script passing along a json to stdin with the incident informations. The called script can apply any type of checks/sideffects and output another json to stout to answer the call.
Even though rules can be written in any language it's very straightforward using python:
### Rules: an example
An example rule can be written in python with the following lines
```python
#!/usr/bin/env python3
from pdh import rules, Filter@rules.rule
def main(input):
return {i["id"]: i["summary"] for i in input}if __name__ == "__main__":
main()
```This is the simplest rule you can write, reading the input and simply output a new dictionary with the entries. It will output something like:
```bash
pdh inc apply Q1LNI5LNM7RZ2C Q1C5KG41H0SZAM -s ./a.py
┏━━━━━━━━┳━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┳━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┓
┃ script ┃ Q1LNI5LNM7RZ2C ┃ Q1C5KG41H0SZAM ┃
┡━━━━━━━━╇━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━╇━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┩
│ ./a.py │ AWS Health Event: us-east-1 EC2 : AWS_EC2_INSTANCE_STOP_SCHEDULED │ AWS Health Event: us-east-1 EC2 : AWS_EC2_INSTANCE_STORE_DRIVE_PERFORMANCE_DEGRADED │
└────────┴────────────────────────────────────────────────────────────────────┴──────────────────────────────────────────────────────────────────────────────────────┘
```The default output is `table` with one line for each script runned and with one column per each element in the returned object
### Rules: more examples
```python
#!/usr/bin/env python3# Needed imports
from pdh import rules, Filter# This annotation make the main() method parse stdin as json into the parameter called input
# All returned values are converted to json and printed to stdout
@rules.rule
def main(input):# Initialize PagerDuty's APIs
api = rules.api()# From the given input extract only incidents with the word cassandra in title
incs = Filter.objects(input, filters=[Filter.regexp("title", ".*EC2.*")])# ackwnoledge all previously filtered incidents
api.ack(incs)# resolve all previously filtered incidents
api.resolve(incs)# snooze all previously filtered incidents for 1h
api.snooze(incs, duration=3600)# Chain a given rule, i.e call that rule with the output of this one
# chain-loading supports only a single binary, not directories
c = rules.chain(incs, "rules/test_chaining.sh")# Execute an external program and get the output/err/return code
p: rules.ShellResponse = rules.exec('kubectl get nodes -o name')
if p.rc > 0:
nodes = p.stdout.split("\n")# if you return a dict will be rendered with each item as a column in a table
# Othrwise will be converted as string
return {i["id"]: i["summary"] for i in incs}if __name__ == "__main__":
main()```
## Requirements
- [Taskfile](https://taskfile.dev)
- Python >=3.10
- Docker## Contributing
First of all you need to setup the dev environment, using Taskfile:
```bash
task setup
```This will create a python virtualenv and install `pre-commit` and `poetry` in your system if you lack them.
