Hear It Before It Happens — Inside WAP's Monitoring & Alerting Module

The Other Half Everyone Forgets

Monitoring isn't the problem. Monitoring nobody responds to is.

Most teams stop at "we have a dashboard" — the charts look great, but nobody's actually watching them. Alerts get configured once and then either fire too often, training everyone to mute the channel, or fire too late, arriving well after the incident has already unfolded.

A threshold gets set once and never revisited — the business triples in scale, and the alert line is still where it started

A 3 a.m. alert says nothing more than "CPU is high," with zero context, leaving the on-call engineer to dig from scratch

Too many alerts, too much noise — the team quietly muted the notification channel a long time ago

01 · Full-Dimension Coverage

See everything, so you can see accurately

WAP collects metrics from both the host and the MongoDB instance layer — from basic CPU, memory, and disk I/O, to connection counts, replication lag, lock waits, and slow-query share — every metric recorded second by second, never sampled or estimated.

Host-Level Metrics

CPU · Memory · Disk I/O · Network Throughput

Instance-Level Metrics

Connections · Queue Length · Opcounters · Cache Hit Rate

Replication Health

Election Frequency · Oplog Lag · Heartbeat Status

Query-Level Metrics

Slow Query Share · Lock Wait Time · Scan Efficiency

Detail Metrics

Detailed Monitoring Metrics

Every metric visualized — anomalies visible at a glance.

02 · Tiered Alerting

Alerting isn't "sending a notification"

A genuinely useful alerting system isn't really about the trigger condition — it's about tiered response. The same CPU spike happening during a quiet Tuesday afternoon and during peak traffic deserves a completely different response path.

03 · From Alert to Root Cause

By the time the alert fires, the reason is already on screen

Most alerting systems only shout "something's wrong" and leave the investigation to a human. WAP attaches context automatically — collapsing "spot the problem" and "find the cause" into a single step.

[ALERT] Shard shard02 replication lag hit 128ms, over the 100ms threshold
[CORRELATED] Disk I/O utilization on this node rose to 92% in the same window
[ROOT CAUSE] Most likely a disk I/O bottleneck delaying oplog application

            [SUGGEST]
            Check this node's disk queue depth, or temporarily lower its read traffic weight to relieve pressure.
