| View | What it shows |
|---|---|
| Host map | One tile per host, colored by the selected metric from green to red. Spot hot hosts at a glance. |
| Rings | One ring gauge per host. |
| List | A table with status, OS, CPU, memory, fullest disk, files followed, agent version and last seen. |
Fill by and group by
- Fill by picks the metric that colors the map: CPU %, Memory %, Disk % (fullest disk) or Swap %.
- Group by splits the map into groups: by any tag key (for example
env,roleorteam), by OS, or by status.
Tags come from agent.tags in each host's logcore.yaml, so a consistent tagging scheme such as env, role and team makes the map much more useful.
Filters
- The search box matches the hostname, OS and tags, for example
env:prod web. - Side facets: Status (online or offline), OS, and one facet per tag key.
The summary bar shows online and offline counts and the average of the "fill by" metric for the hosts you're viewing.
Host page
Click a host to open its page:
- Overview: current CPU, memory, fullest disk, uptime and agent version.
- Charts: CPU, memory, disk, network traffic and load (1 min) over the selected range.
- Services: the log services configured on the host, with their files.
- Disks: usage per mount point.
- Host & agent: OS, platform, kernel, agent version, tags and last seen.
- Remove: deletes the host and its metrics. Logs stay until they expire. If the agent is still running, the host comes back the next time it reports.
Online and offline
The agent sends a heartbeat every 30 seconds. A host that hasn't reported for 2 minutes is shown as Offline. To get notified, create a host offline monitor.
Metrics collected
| Metric | Details |
|---|---|
| CPU | Total utilization % |
| Memory | Used %, used and total bytes |
| Swap | Used % |
| Disk | Used % per mount point; the map uses the fullest disk |
| Load | 1, 5 and 15 minute load averages (Linux) |
| Network | Bytes sent and received per second |
| Uptime | Since boot |
They're sampled every 15 seconds by default (metrics.interval) and kept for 30 days.
