Cases

When something goes wrong, the signals rarely arrive as a single tidy alert. You get a cluster of events across several devices, a few suspicious log lines, and maybe a service that started timing out — all part of the same underlying problem. A Case is the container that ties those pieces together so one person can own the investigation, gather the evidence, write down what they found, and drive it to a fix.

The Cases page The Cases page lists open investigations with their status, severity, assignee, and how many events each one groups.

Think of a case as an investigation file. Instead of chasing a dozen separate alerts, you pull the related ones into a single case and work the problem in one place. A case keeps together:

  • The events that belong to the same incident.
  • The devices affected.
  • A timeline of evidence — log lines, metric readings, and notes, in order.
  • The findings and remediation you write up as you go.
  • The status, severity, owner, and assignee so the team knows where it stands.

Open Investigate → Cases. The list shows every case with its status, severity, assignee, the number of events it groups, and how it was created. Click a row to open the case workbench — the full detail view where the investigation happens. A search box and status filters help you find a specific case in a long list.

Cases come into existence two ways:

GridNMS opens cases for you when activity correlates:

  • From a detection — a detection can be set to open a case on match, so a meaningful pattern in your logs becomes a ready-made investigation instead of just another event.
  • From correlated activity — when related events cluster together, GridNMS can group them into a single case automatically rather than leaving you to connect the dots.

Auto-created cases are labelled by origin (for example Detector or Correlated) so you can tell at a glance which were machine-generated.

Click New Case to start one yourself when you’ve spotted something worth investigating. Give it a title, a severity, and a short description, then start attaching evidence. Manually created cases are labelled Manual.

Opening a case gives you a working surface built around the investigation.

At the top you set where the case stands and who’s on it:

Status Meaning
Open New — not yet being worked.
Investigating Someone is actively working it.
Resolved The problem is fixed; pending final close.
Closed Done and archived.

You can also set the severity, assign the case to a person, and add tags to group related work. Assignment and status are the two things teammates look at first, so keep them current.

The case lists the events rolled into it. You can attach more events by browsing or searching — optionally limited to just the devices already on the case — and detach any that turn out not to belong. The devices involved are tracked alongside, giving you the full blast radius in one view.

The heart of the workbench is a timeline you build as you investigate. From within the case you can browse and pin evidence directly onto it:

  • Log lines — search across your logs (optionally scoped to a device) and attach the relevant lines as timeline entries.
  • Metric data points — chart a device metric or a monitored service’s response time over a fixed window, then log a specific point onto the timeline to capture exactly what a value was at a moment that matters.
  • Alarms — attach a threshold alarm that fired as part of the story.

Each pinned item lands on the timeline with its timestamp, building an ordered, evidence-backed account of what happened and when.

Alongside the timeline you keep the narrative: free-form notes as you work, a summary of what you found, and the remediation — what was done (or needs to be done) to resolve it. This is what turns a closed case into something useful later: the next person who hits a similar problem can read exactly how this one was handled. An activity log records the case’s own history — status changes, assignments, and attachments — automatically.

When the problem is fixed and written up, set the status to Resolved and then Closed. Closing records who closed it and when. A closed case stays fully searchable, so it becomes part of your team’s institutional memory — a record of what broke, how you knew, and how you fixed it.
