The Scheduler service
made by etke.cc

Introduction

Introducing The Scheduler, a dedicated maintenance system tailored for etke.cc customers. This exclusive tool empowers you with the ability to manage essential server maintenance tasks and tackle common challenges like handling disk usage and service restarts.

Customize Your Experience

One of the unique features of The Scheduler is its flexibility, allowing you to select from different stability branches and maintenance timeframe for your homeserver. This customization enables you to align your maintenance process with your specific requirements.

Getting Started

Initiating and using The Scheduler is straightforward. Simply initiate a chat with @scheduler:etke.cc and send the command help to access detailed instructions.

Note: The Scheduler bot exclusively serves etke.cc customers, making it an invaluable resource for your server management needs.

Four Work Modes

The Scheduler supports four distinct work modes, each designed to cater to specific tasks and needs. While you can utilize all modes simultaneously, it is recommended to employ recurring maintenance to ensure your server remains up to date and protected.

Run

The run mode immediately executes a command , providing rapid results. For instance:

  • @customer: run ping
  • @scheduler: Command execution initiated. Please be patient, as this may take some time. You’ll receive a notification upon completion.
  • @scheduler: Execution of run ping command successful
INFO [etke.cc] disk usage: 85%

Explore the full list of available commands here .

Schedule

The schedule mode allows you to plan a command for a specific date and time (UTC). For example, scheduling maintenance for July 1st at 5 pm UTC:

  • @customer: schedule maintenance 2022-07-01 17:00
  • @scheduler: Command scheduled.

On July 1st, around 5:30 pm UTC (accounting for the duration of maintenance), you will receive the following message:

The schedule mode essentially schedules the run mode for a specified future date and time.

Recurring

The recurring mode configures specific weekdays and times for recurring schedule mode commands. By default, automatic maintenance is scheduled to a random weekday and time. This mode simplifies recurring tasks, automatically creating corresponding schedules for executing the chosen command at specific times on specified weekdays. For example, setting up server maintenance every Friday at 3 pm UTC:

  • @customer: recurring maintenance Friday 15:00
  • @scheduler: Recurring schedule configured.

Every Friday, around 3:30 pm UTC (considering maintenance duration), you will receive this message:

  • @scheduler: Execution of run maintenance command successful

Note: You can set only one recurring schedule per command (e.g., one recurring maintenance). Multiple recurring configurations for the same command will replace one another, leaving you with a single recurring configuration (the last one) — for example, on Monday at 5 pm UTC.

List

The list mode serves as a useful tool for reviewing your executed commands, scheduled tasks, and recurring schedules. It is especially handy when you need to check specific information. Here are some examples:

  • @customer: list runs
  • @scheduler:
* 2022-06-12 16:36: run ping
* 2022-05-30 22:01: run maintenance
* 2022-06-19 16:03: run restart slack failed: exit status 1
  • @customer: list schedules
  • @scheduler:
* 2022-06-27 16:00: run ping (recurring)
* 2022-07-01 17:00: run ping

Note: The (recurring) suffix indicates that the task is automatically scheduled because it is part of a (weekly) recurring schedule. It shows the nearest future recurrence date.

  • @customer: list recurring
  • @scheduler:
* Monday 16:00: run ping

Alert

In addition to its server management capabilities, The Scheduler proactively sends alerts when issues arise with your server. These alerts can include notifications about high disk usage or unreachable API endpoints on your Matrix server.

More details about the monitoring system is available on the Monitoring page.

Please note that The Scheduler will automatically initiate a chat with you if you don’t already have one set up.

Commands

Command List

The Scheduler provides several essential commands to address various server management needs:

ping

The ping command checks server reachability and disk utilization. It’s especially useful when configuring a new firewall or ensuring you have sufficient storage for those important cat photos.

Example:

  • @customer: run ping
  • @scheduler: Command execution initiated. Please be patient; you will receive a notification upon completion.
  • @scheduler: Execution of run ping command successful
INFO [etke.cc] disk usage: 85%

More details about the monitoring system and checked parameters is available on the Monitoring page.

disk

The disk command assesses disk utilization for common server components, providing valuable insights when disk usage is a concern.

Example:

  • @customer: run disk
  • @scheduler: Command execution initiated. Please be patient; you will receive a notification upon completion.
  • @scheduler: Execution of run disk command successful
INFO [etke.cc] disk usage: 65%
INFO [etke.cc] Database: 5.9G
INFO [etke.cc] Database backups: 8.6G
INFO [etke.cc] Media: 3.8G

price

The price command provides an overview of your server’s cost with detailed breakdown by components. You may request changes to your server configuration or additional services based on this information, just contact us

Example:

  • @customer: run price
  • @scheduler: Command execution initiated. Please be patient; you will receive a notification upon completion.
  • @scheduler: Execution of run price command successful

The total price for your server is $65

Here is the detailed breakdown (free items are skipped):

  • BorgBackup : $3 The "Holy Grail" of backups (requires a separate Borg backup provider)
  • Matrix : $5 Base components and services for any server
  • Email service : $5 A fully-featured multi-user email service for your domain (you@domain.com ), powered by Migadu. SMTP Relay is included at no extra cost.
  • Hosting (Big) : $25 The VPS where your Matrix server is hosted
  • GoToSocial : $3 A fast, fun, ActivityPub server
  • Buscarron : $3 A bot that receives web form submissions (HTML/HTTP POST) and sends them to (encrypted) Matrix rooms
  • Honoroit : $3 A helpdesk bot with end-to-end encryption support
  • Bridges : $5 With the help of bridges, you can access different networks right from your own Matrix server
  • Synapse Single Sign-On : $5 Log in to Matrix with an OpenID provider as a backend (Auth0, Google, Github, Gitlab, Okta, etc.)
  • Synapse Workers : $5 A multi-process homeserver setup to more efficiently handle many users and large rooms. Requires a powerful server (8+ GB of RAM)
  • Miniflux : $1 A minimalist and opinionated feed reader
  • Ntfy : $1 UnifiedPush provider for (private) push notifications
  • Radicale : $1 Free and Open-Source CalDAV and CardDAV Server

maintenance

This command triggers the maintenance process, which typically takes 15-30 minutes to complete. You can find further details on the services page.

Example:

  • @customer: run maintenance
  • @scheduler: Command execution initiated. Please be patient; you will receive a notification upon completion.
  • @scheduler: Execution of run maintenance command successful

restart

The restart command serves to restart a systemd service, particularly helpful when a bridge is unresponsive. It features an internal mapping between “user-friendly” service names and actual service names. For instance, if you wish to restart the Facebook bridge, you can use run restart facebook instead of specifying run restart matrix-mautrix-facebook (although the latter is equally valid).

Example:

  • @customer: run restart slack
  • @scheduler: Command execution initiated. Please be patient; you will receive a notification upon completion.
  • @scheduler: Execution of run restart slack command successful

Note: In the schedule and recurring modes, the restart command must be placed after the date/weekday and time. For example, you can use schedule restart 2022-07-01 17:00 slack or recurring restart Monday 17:00 slack.

Stability Branches

The Scheduler acknowledges that customers have varying preferences when it comes to the stability of updates. To cater to these preferences, we offer different stability branches to choose from. If you wish to switch to an alternative stability branch for your homeserver, kindly contact us for assistance.

stable (default)

The stable branch, as its name implies, is the go-to choice for stability and reliability. It features well-tested updates and typically lags a few days (up to a week) behind the fresh branch.

With stable as your default stability branch, we gather component updates throughout the week. We conduct extensive testing on developer servers, open-source community members’ servers, and customer servers specifically opted into the fresh stability branch. Once we’re confident in the stability of these updates, they are published in the stable branch, ensuring they won’t disrupt your server when installed during maintenance.

stable serves as the default stability branch for all customer servers unless customers explicitly request to use fresh.

fresh (testing)

The fresh branch is designed for those who crave the latest updates as soon as possible. Updates arrive in this branch without delay, often a week earlier than stable. While fresh updates might contain breaking changes, we typically prepare workarounds and migrations in advance.

To access updates quickly, even at the risk of encountering occasional breakage, choose the fresh stability branch. Note that real-time updates are available in the dedicated room #fresh:etke.cc , while the current differences between fresh and stable are detailed in the VERSIONS.diff.md in the repository
