## Introduction

Using a single terminal command, `slurm-viewer` allows you to view the status of your SLURM cluster (i.e., nodes and jobs). This command combines information from SLURM commands like `sinfo`, `scontrol`, `squeue` and `sacct` in a tabular and customizable view.

This command line application can be run on the cluster itself or any computer that can ssh into the cluster.

## Features
- **Single command**: The `slurm-viewer` command allows you to view the status of nodes and jobs in your SLURM cluster.
    - **Multiple Clusters**: View multiple clusters in a single interface.
    - **SSH Tunneling**: Connect to the cluster using a jumphost/gateway.
- **Intuitive Interface**: `slurm-viewer` presents all node/job information in a tabular format.
- **Customizable Interface**: Filter and sort nodes and jobs based on various criteria like partitions and GPU availability
- **Resource Utilization Plots**: View the GPU memory/utilization used over the last 4 weeks.

## Installation

```bash
pip install slurm-viewer
```
or
```bash
uvx slurm-viewer
```

## Usage

- Run `slurm-viewer` to start the UI.
- Upon the first run, a default settings file will be created in `~/.config/slurm-viewer/settings.toml`. Edit this file to reflect your setup.

## Settings
The `settings.toml` config file allows for defining which clusters you want to connect to and also user preferences on which columns to display.
The location of the used settings file can be found in the help window.\
The primary tags are `ui` and `clusters`.

### UI
In the `ui` section you can define which columns to display for nodes (`node_columns`), queue (`queue_columns`) and priority (`priority_columns`) views. The columns are defined as a list of strings.\
Although the UI allows the reordering of columns it is easier to edit the settings.toml and reload the config using `F3`. That way the order is preserved for the next time.

### Clusters
In the `clusters` section you can define the clusters you want to connect to. Each cluster has the following tags:
- `name`: A user-defined name of the cluster.
- `partitions`: A list of partitions you are interested to view in the cluster.
- `tabs`: A list of tabs to display in the UI. The options are `nodes`, `jobs`, `gpu` and `status`.
- `node_name_ignore_prefix`: A list of prefixes to ignore in the node names.
    - For e.g. if the node names are `node-1`, `node-2`, `node-3`, you can ignore the `node-` prefix by setting `node_name_ignore_prefix = ["node"]`
- `servers`: A list of servers to connect to the cluster itself. A cluster can have multiple servers defined, they will be tried in order and the first server that connects will be used.
    - If you have a jumphost/gateway, use the `~/.ssh/config` to set up the connections and use the `Host` name as the server.
      `status`


```toml
[ui]
node_columns = ["node_name", "state", "gpu_tot", "gpu_alloc", "gpu_avail", "gpu_type", "gpu_mem", "cpu_tot", "cpu_alloc", "cpu_avail", "mem_tot", "mem_alloc", "mem_avail", "cpu_gpu", "mem_gpu", "cpuload", "partitions", "active_features"]
queue_columns = ["user", "job_id", "reason", "exec_host", "start_delay", "run_time", "time_limit", "command"]
priority_columns = ["user_name", "job_id", "job_priority_n", "age_n", "fair_share_n", "partition_name"]

refresh_interval = 10 # Interval in seconds when auto refresh is enabled
auto_refresh = "False" # Automatically refresh 'nodes' and 'queue' tabs at the given interval
user_only = "False" # Start with data for the user only or all users of the cluster

[[clusters]]
name = "cluster_1"
partitions = ["partition-cpu", "partition-gpu"]
tabs=["nodes", "jobs", "gpu", "status"]
node_name_ignore_prefix = [""]
servers = ["cluster_1_logon_node_1", "cluster_1_logon_node_2"]

[[clusters]]
name = "cluster_2"
partitions = ["cpu-short", "cpu-medium", "cpu-long", "gpu-short", "gpu-medium", "gpu-long"]
node_name_ignore_prefix = ["node"]
server = "gateway_1"
```

If you need to connect using a jumphost/gateway use the `~/.ssh/config` to setup the connections and use the `Host` name as
the server.

Example of an ssh config:

```
Host gateway_1
  User my_user_name
  HostName gateway.somewhere
  
Host cluster_1_logon_node_1
  User my_user_name
  HostName logonnode.somewhere
  ProxyCommand ssh -W %h:%p gateway_1
```
