On-Call Log

Pull alerts from your monitoring platform and create a structured on-call log on your team's wiki.

When to Use

• End of your on-call shift — log what happened for the next engineer
• Daily or weekly on-call review meetings
• Building a history of alert patterns over time

Process

1. Verify MCP Server Availability

Two MCP servers are required:

1. Monitoring MCP — to fetch alert events and monitor status. Recommended: Datadog MCP.
2. Wiki MCP — to create the log page. Supported: Confluence (mcp__claude_ai_Atlassian__*) or Notion (mcp__claude_ai_Notion__*).

If either is missing, stop with:

Error: Missing required MCP server(s): <list>. This skill needs both a monitoring MCP and a wiki MCP. Recommended: Datadog MCP + Confluence or Notion MCP.

2. Gather Configuration

Ask the user:

1. Log frequency — daily or weekly? (default: weekly)
2. On-call rotation schedule — what day does the rotation start? (default: Friday, only relevant for weekly)
3. Environment filter — which environments to include? (default: prod only)
4. Wiki space/parent — where to create the log page:
   • Confluence: space key and parent page ID
   • Notion: parent page ID or database ID
5. Template page (optional) — an existing page to use as format reference

If the user has run this before and configuration is available (e.g., in .spartan/config.yaml), reuse those settings and confirm:

"Using previous settings: <frequency>, <env> alerts, wiki at <location>. Correct?"

3. Determine Date Range

Based on the log frequency from Step 2:

• Daily: today (or a specific date if the user provides one)
• Weekly: calculate the on-call window based on the rotation day (e.g., Friday to Friday)

If the user provides a custom date range, use that instead.

Confirm with the user:

"Logging on-call for <start date> – <end date>. Is this correct?"

Wait for confirmation before continuing.

4. Fetch Alerts from Monitoring

4a. Check for existing page (incremental update)

Search the wiki for an existing page for this period (using the naming convention from Step 7). If found, read it to find the last updated timestamp. Ask the user: "A page for this period already exists. Update it or create new?"

• If update: use the last updated timestamp as the from date instead of the full window start — this avoids re-fetching alerts already logged and reduces token usage.
• If create new: use the full window start and create a separate page in Step 8.

Add a **Last updated:** <timestamp> line at the top of the page on each update.

4b. Query triggered alert events

Use the available monitoring MCP to fetch alert events:

• Filter by environment + triggered/warn status
• Time range: from last update (or window start if new page) to now
• Sort by timestamp

Pagination: If results are truncated, paginate until all events are fetched.

4c. Filter and normalize

From all fetched events:

• Exclude events from non-target environments
• Exclude recovery events — only count triggered and warn events
• Normalize monitor titles: strip status prefixes to get the base monitor name

4d. Build the alert summary

Group events by base monitor name. For each group collect:

1. Appear Count — total trigger events for that monitor during the window
2. Appear Times — each trigger timestamp, with a link to the event in the monitoring platform
3. Current Status — is the monitor still in Alert status right now?

Sort alerts by Appear Count descending.

4e. Check currently active monitors

Query monitors currently in Alert status. Flag these as needing follow-up by the next on-call.

If no alerts during the window, note "No alerts this period" and continue.

5. Ask for Additional Notes

"Any additional notes, incidents, or action items to include in the log?"

Record their input. If "none", continue without notes.

6. Fetch Template (if configured)

If the user provided a template page in Step 2, fetch it and use its structure as the format guide. Otherwise use the default structure from Step 8.

7. Find or Create the Target Location

Organize on-call logs in a consistent hierarchy:

On-call Logs/
  On-call <YYYY>/
    On-call <MM>/<YYYY>/
      [On-call] <Start Date> - <End Date>

1. Check if the year folder exists — create if missing
2. Check if the month folder exists — create if missing
3. Check if a page for this period already exists:
   • If found and user chose update in Step 4a: update this page in Step 8
   • If found and user chose create new in Step 4a: create a new page in Step 8
   • If not found: proceed to Step 8

8. Create the Log Page

Create the page on the wiki platform:

# On-call Log: <Start Date> – <End Date>

## Alert Summary

| Alert | Count | Times | Cause | Resolution |
|-------|-------|-------|-------|------------|
| <monitor name> | <N> | <timestamp 1>, <timestamp 2>, ... | | Still active |

**Total alerts:** <N> across <M> unique monitors

## Currently Active Alerts
<list monitors still in Alert status, or "None — all clear">

## Notes
<additional notes from Step 5, or "None">

## Action Items for Next On-call
- <follow up on active alert X>
- <investigate recurring alert Y — triggered N times>

Formatting:

• Link alert names to their monitoring page
• Link timestamps to the specific event
• Leave "Cause" column empty for the engineer to fill post-hoc
• Set "Resolution" to "Still active" for monitors currently in Alert status; leave empty for resolved monitors (engineer fills post-hoc)

9. Present Result

## On-call Log Created

**Page:** <page title>
**URL:** <wiki page URL>
**Alerts logged:** <N> alerts across <M> unique monitors
**Active alerts:** <count or "None">
**Notes:** <summary or "None">

If there are unresolved alerts:

Action items for next on-call: The following alerts are still active — follow up with the relevant team: <list>

Interaction Style

• Confirm configuration and date range before fetching — don't assume
• Ask one round of questions, not multiple back-and-forth
• Present the final page URL prominently so the user can share it immediately

Rules

• Always confirm the date range before fetching alerts
• Only include production alerts unless the user explicitly asks for other environments
• Never create duplicate wiki pages — check for existing ones first
• Leave "Cause" column empty — the engineer fills it post-hoc. Set "Resolution" to "Still active" for active monitors, leave empty for resolved ones
• Paginate fully — do not present partial alert data

Output

Create the log page directly on the wiki platform (Confluence or Notion). Present the URL and stats inline in the conversation.
