SolarWinds Log Analyzer — Collecting and Making Sense of Logs
SolarWinds Log Analyzer is aimed at a pretty specific pain point: logs everywhere, no time to read them. Windows Event Viewer, syslog streams, SNMP traps — they all pile up. This tool pulls them into one place and makes them searchable. It’s not a full SIEM, more like a bridge between raw log data and the monitoring dashboards many teams already run inside the SolarWinds Orion platform.
Why It Matters
Admins usually notice the problem only after something breaks. A server goes down, a login storm starts, or a switch begins spitting errors — and the only clue is buried in a text log. Instead of hopping between machines, Log Analyzer gives a single screen where those entries show up in real time. For companies already using Orion, it drops in without much extra work and extends the monitoring setup to include log visibility.
How It Works
– Collects syslog messages, SNMP traps, and Windows Event Logs.
– Saves them into SQL Server with indexing so searches run fast.
– Dashboards show both summaries and raw entries, with drill-down when needed.
– Rules highlight warnings or critical errors, while alerts tie into the SolarWinds notification engine.
Deployment / Installation Guide
– Runs on Windows Server, installed via the SolarWinds Orion setup wizard.
– Once installed, devices are added from the Orion web console.
– As soon as sources are defined, logs start streaming in.
– Works best when paired with other SolarWinds modules like Network Performance Monitor.
Integrations
– Native connection with other Orion modules.
– Alerts can flow into email, scripts, or ticketing systems.
– Collects syslog from routers, switches, firewalls; Windows logs from servers.
– Can be used alongside performance metrics for better troubleshooting context.
Real-World Applications
– Keeping all Windows and network logs in one searchable database.
– Checking failed logins or repeated restarts across servers.
– Investigating compliance events that require retention.
– Linking performance drops with log messages during outages.
Limitations
– Works only on Windows Server.
– Needs SQL Server for storage, which can get heavy on big deployments.
– More footprint than simple log shippers.
– Paid licensing makes it less appealing for very small shops.
