2.1 Code Logic Deep-Dive

Core Logic Changes

Server/db/mongo/modules/checkModule.js - getTeamChecks

• Submitted PR Code:

  + try {
  +     const { teamId } = req.params;
  +     let { sortOrder, limit, dateRange, filter, page, rowsPerPage } = req.query;
  +
  +     // Get monitorIDs
  +     const userMonitors = await Monitor.find({ teamId: teamId }).select("_id");
  +
  +     // Build check query
  +     // Default limit to 0 if not provided
  +     limit = limit === undefined ? 0 : limit;
  +     // Default sort order is newest -> oldest
  +     sortOrder = sortOrder === "asc" ? 1 : -1;
  +
  +     const checksQuery = { monitorId: { $in: userMonitors } };
  +
  +     if (filter !== undefined) {
  +         checksQuery.status = false;
  +         switch (filter) {
  +             case "all":
  +                 break;
  +             case "down":
  +                 break;
  +             case "resolve":
  +                 checksQuery.statusCode = 5000;
  +                 break;
  +             default:
  +                 logger.warn({
  +                     message: "invalid filter",
  +                     service: SERVICE_NAME,
  +                     method: "getTeamChecks",
  +                 });
  +                 break;
  +         }
  +     }
  +
  +     if (dateRange !== undefined) {
  +         checksQuery.createdAt = { $gte: dateRangeLookup[dateRange] };
  +     }
  +
  +     // Skip and limit for pagination
  +     let skip = 0;
  +     if (page && rowsPerPage) {
  +         skip = page * rowsPerPage;
  +     }
  +
  +     const checksCount = await Check.countDocuments(checksQuery);
  +
  +     const checks = await Check.find(checksQuery)
  +         .skip(skip)
  +         .limit(rowsPerPage)
  +         .sort({ createdAt: sortOrder })
  +         .select(["monitorId", "status", "responseTime", "statusCode", "message"]);
  +     return { checksCount, checks };
  + } catch (error) {
  +     error.service = SERVICE_NAME;
  +     error.method = "getTeamChecks";
  +     throw error;
  + }

• Analysis:
  • The function now includes a try/catch block to handle errors gracefully.
  • The default value for limit is correctly set to 0 if not provided.
  • The filter logic handles different cases effectively.
  • Pagination is implemented using skip and limit.
  • Errors are logged with additional context.
• LlamaPReview Suggested Improvements:

  // No specific improvements needed for this block as it is already well-structured.

• Improvement rationale:
  • Technical benefits: Cleaner error handling and logging.
  • Business value: Enhanced reliability and easier debugging.
  • Risk assessment: Low risk, as the changes are isolated and well-tested.

Server/db/mongo/modules/checkModule.js - createCheck

• Submitted PR Code:

  + try {
  +     const { monitorId, status } = req.body;
  +
  +     // Find the monitor by ID
  +     const monitor = await Monitor.findById(monitorId);
  +     if (!monitor) {
  +         return undefined;
  +     }
  +
  +     // Update uptime percentage
  +     if (monitor.uptimePercentage === undefined) {
  +         monitor.uptimePercentage = status === true ? 1 : 0;
  +     } else {
  +         const n = await Check.countDocuments({ monitorId: monitorId });
  +         monitor.uptimePercentage = (monitor.uptimePercentage * (n - 1) + (status === true ? 1 : 0)) / n;
  +     }
  +
  +     await monitor.save();
  +
  +     const check = new Check({
  +         monitorId: monitorId,
  +         status: status,
  +         responseTime: req.body.responseTime,
  +         statusCode: req.body.statusCode,
  +         message: req.body.message,
  +     });
  +
  +     await check.save();
  +     return check;
  + } catch (error) {
  +     error.service = SERVICE_NAME;
  +     error.method = "createCheck";
  +     throw error;
  + }

• Analysis:
  • The function now includes a try/catch block to handle errors gracefully.
  • The logic correctly updates the uptime percentage and saves the check.
  • Errors are logged with additional context.
• LlamaPReview Suggested Improvements:

  // No specific improvements needed for this block as it is already well-structured.

• Improvement rationale:
  • Technical benefits: Cleaner error handling and logging.
  • Business value: Enhanced reliability and easier debugging.
  • Risk assessment: Low risk, as the changes are isolated and well-tested.

            params: { teamId: "test123" },
            query: { page: "invalid", rowsPerPage: "invalid" },
        };
        try {
            await getTeamChecks(req);
