Read-only log search and aggregation for VMware Aria Operations for Logs (formerly vRealize Log Insight) — the appliance that collects syslog from ESXi hosts, vCenter, and VMs. The centralized-log data source for the VMware skill family. Strictly non-destructive: it queries, it never writes.

Companion Skills

Need	Skill	Tools
Raw centralized logs + spikes	vmware-log-insight (this)	7
vCenter events & alarms	vmware-monitor	27
Metrics, anomalies, capacity	vmware-aria	28
Incident correlation / root cause	vmware-debug — feed it `log_search` output	2
VM lifecycle / operations	vmware-aiops	49

Install

bash

uv tool install vmware-log-insight
mkdir -p ~/.vmware-log-insight
cp config.example.yaml ~/.vmware-log-insight/config.yaml   # edit host/username/provider
echo 'VMWARE_LOG_INSIGHT_PROD_PASSWORD=...' > ~/.vmware-log-insight/.env
chmod 600 ~/.vmware-log-insight/.env
vmware-log-insight doctor

Offline / Air-Gapped Install (from source)

This project uses the modern PEP 517 build system (hatchling), so there is no setup.py by design — that is expected, not a missing file. If you cloned the source and hit ERROR: File "setup.py" or "setup.cfg" not found ... editable mode currently requires a setuptools-based build, your pip is older than 21.3 and cannot do an editable (-e) install with a non-setuptools backend. Editable mode is a developer convenience, not needed to run the tool — do one of:

bash

# From the source tree — a normal (non-editable) install builds a wheel:
pip install .              # NOT  pip install -e .

# ...or upgrade pip first, and editable works too:
pip install --upgrade pip && pip install -e .

For a truly air-gapped host, build the wheels on a connected machine and copy them over — the target then needs no network:

bash

# On a connected machine, collect this package + its dependencies as wheels:
pip wheel . -w dist        # → dist/*.whl   (or: uv build, for just this package)

# Copy dist/ to the air-gapped host, then install offline:
pip install --no-index --find-links dist vmware-log-insight

MCP Tools (7 — all read-only)

Tool	What
`log_search`	Search events by time window + text + filters
`log_aggregate`	Count/aggregate over time bins, with z-score spike detection
`log_fields`	List extracted fields usable in filters
`log_version`	Appliance version/build
`alert_list` / `alert_get` / `alert_history`	Query defined alerts and their trigger history

Workflows

Find errors fast — vmware-log-insight search -q error -l 1h.
Where did logs burst? — vmware-log-insight aggregate -q error -l 6h --bin-ms 300000, read spikes[], then search the spike window.
Root cause — pass log_search results (plus vCenter events from vmware-monitor and metrics from vmware-aria) to vmware-debug incident_timeline.

Troubleshooting

401 on /sessions → check username/password/provider and the VMWARE_LOG_INSIGHT_<TARGET>_PASSWORD env var.
503 everywhere → appliance starting up; doctor reports it as a status, not a crash.
Empty results → widen --last; default API port is 9543 (set port if different).

Security

Read-only by construction. Credentials in ~/.vmware-log-insight/.env (chmod 600); plaintext passwords auto-obfuscated to grep-safe b64: (obfuscation, not encryption — inject from a secret manager for real secrecy). TLS on by default. See SECURITY.md.
