deferred maintenance CLI

Maintenance that is never performed is a risk to our systems.

There are many vectors where "maintenance debt" can accrue in modern systems:

• Non-critical software dependency updates are available.
• Host system patches should be applied.
• Refactoring toward updated coding standards or best practices.
• Cross-cutting changes to infrastructure configuration.
• etc.

Individually, for small systems, completing these tasks are a minor chore. For large systems and microservices architectures that might span many hundreds of code repositories, completing these tasks becomes much more challenging.

Often, efforts to perform maintenance work can seem lower priority, and as such have a tendency to quickly become "out of sight, out of mind". What is needed is a way to store the notion of a maintenance task to be deferred in such a way that it helps us reason transparently about the risk to our overall systems, and remains quickly actionable by the person who decides to take action on the work. It has been our experience that storing maintenance tasks in issue trackers like Jira is better than nothing, but doesn't help us reason quickly about the overall risk such maintenance debt is contributing.

deferred-maintenance is a simple CLI tool for managing this maintenance debt and risk using the JupiterOne graph.

Installation and Setup

Install with npm install -g @jupiterone/deferred-maintenance.

You will need to either export the following vars, or set them up in a ~/.env file:

J1_ACCOUNT=<your account name>
J1_API_TOKEN=<your full J1 api token>
J1_EMAIL=<email address associated with your J1 user>

Make sure to chmod 0700 ~/.env!

Usage

Running deferred-maintenance with no arguments will generate a report of maintenance that has been opened against your current git repository, if you happen to be in one that JupiterOne knows about. If you specify -d | --debug, it will also show you any open maintenance findings you have created previously. Example output:

~/repos/jupiterone-client-nodejs master
❯ deferred-maintenance --debug
Gathering maintenance report...

OK

The maintenanceId is a unique id that can help identify these findings in future queries (see below).

Opening Deferred Maintenance

Issuing deferred-maintenance open will interactively prompt you for a J1QL query that targets entities in the graph that you want to open maintenance Findings against. NOTE: for developers, these entities are often CodeRepos, but maintenance tasks might apply to almost anything in the graph. It is recommended that you get a J1QL query working in the JupiterOne landing zone first, to make sure that you target the right entities.

After confirming your entity selection, you'll be prompted for details about the maintenance that needs to be performed:

• shortDescription: a terse description (this will appear in the visual graph for each entity!)
• description: a more verbose description.
• webLink: a link to an issue tracker item or other durable reference that "future us" can use to remember the remediation details.
• dueDate: a reasonable deferment horizon. Maintenance deferred beyond this point should be considered Risk.

Closing Deferred Maintenance

Issuing deferred-maintenance close will interactively prompt you for a J1QL query that targets Finding/deferred_maintenance entities in the graph that you want to close. It is recommended that you get a J1QL query working in the JupiterOne landing zone first, to make sure that you target the right entities.

After confirming your entity selection, you'll be prompted for a web link to a durable record of actions taken (typically, this is a pull request).

Example queries

Check if a given CodeRepo has outstanding risk:

Find deferred_maintenance with closed=false and dueDate < date.now that HAS CodeRepo with name='my-project'

Find all maintenance risk:

Find * as e that HAS deferred_maintenance with closed=false and dueDate < date.now as m return e._type, e.displayName, m.*

Find evidence of maintenance activity for a given entity Class:

Find deferred_maintenance with closed=true as m that HAS SomeClass as c return c.displayName, m.closedOn, m.closedBy, m.maintenanceLink

Further applications of the mechanism

Here are a few ideas that might suggest additional possibilities exposed by this mechanism:

• Evaluating CodeRepo risk at CI/CD (deploy) time.
• Providing compliance evidence of maintenance activity.
• Alerting Slack when maintenance risk count is too high.
