Choose SmokePing for self-hosted historical graphs, PingPlotter for desktop timeline and network-path investigation, or Prometheus Blackbox Exporter with Grafana if you already operate that monitoring stack. These are different deployment options, not products compared in an independent performance test.
Choose a continuous-ping graphing approach
The right option depends mainly on where you want measurements to run and whether you already have a monitoring system. Each graph describes the route from its measurement point to its target, so a graph from a home computer and one from a remote server are not interchangeable.

Use SmokePing for persistent, purpose-built graphs
SmokePing sends several packets in each measurement round, sorts the observed RTTs, and plots the median. The line represents that central value; shaded areas show variation among the probes, while line color conveys packet loss. Its overview and detail graphs also provide values such as average loss, standard deviation, minimum, maximum, and current median. SmokePing: Reading the Graphs
SmokePing’s configuration examples show FPing for regular ICMP measurements, as well as DNS and HTTP probes. These are examples of probe configuration, not current installation instructions. Consult the project’s current documentation for installation and platform-specific setup. SmokePing configuration examples

Use PingPlotter to inspect a reported time window and route
PingPlotter’s Timeline Graph displays latency to the selected hop and packet loss over time. Its documented default is the final hop across the last 10 minutes; you can change the time frame, scroll through the timeline, or focus on an interval around a reported slowdown. The timeline can help establish when measurements changed, while path context can help compare hops. It does not, by itself, prove which device or provider caused a problem.

Use Blackbox Exporter and Grafana if you already use Prometheus
Blackbox Exporter accepts a target as a parameter in Prometheus’s multi-target exporter pattern. It supports ICMP, HTTP/HTTPS, DNS, TCP socket, and gRPC probes. Probe timeouts are based on Prometheus’s scrape_timeout, with an optional timeout limit in the exporter configuration. The Prometheus exporter catalog labels Blackbox Exporter official.

Its author describes an example with a 15-second scrape interval and 20 packets every five minutes as equivalent in resolution to SmokePing; that is the dashboard author’s configuration example, not a universal performance guarantee or independent comparison.

Set up a useful latency history
Before collecting data, decide what question the chart should answer. A graph used to investigate a home internet slowdown needs a known measurement location, a target relevant to the problem, and a time range that includes when the slowdown occurred.

- Pick a stable measurement host. Run the monitor on a computer or server that remains powered and connected. Note where it is located; results represent the path from that host to each target.
- Choose separate targets for local and external checks. A default gateway can help you observe the local network, while a stable external IP address or host can show a different route. Treat the comparison as a diagnostic aid, not proof that either target will respond to ICMP or that a single result identifies the cause.
- Choose the probe that matches the question. ICMP measures ping-style responses. DNS, HTTP/HTTPS, TCP, or gRPC probes test different request-and-response paths; they should not be treated as directly equivalent to ICMP RTT. SmokePing examples demonstrate ICMP, DNS, and HTTP probes, and Blackbox Exporter supports several probe types. SmokePing configuration examples · Blackbox Exporter documentation
- Make the graph interpretable. Record the target, probe type, measurement location, packet count, interval, and retention window. Label the time period and name the statistic being plotted, such as median RTT.
- Keep latency, variation, and loss visible together. A central RTT value alone can hide intermittent spikes or packets that never returned. SmokePing’s graphs show median RTT, variation, and loss; the Grafana Labs dashboard example also describes percentile bands around the median.

Read the graph without overdiagnosing
RTT shows response time along the measured path
Round-trip time is the time for a probe to travel to its target and for a response to return. A consistently high central value looks different from a mostly steady line with occasional spikes, which is why the graph should make its central statistic and time scale clear.
Variation shows how much individual probes differ
A wider spread around the central line indicates more variation among measurements in that round. SmokePing calls the shaded variation “smoke.” Its documentation notes that heavy RTT fluctuation can indicate network overload; this is a possible interpretation, not a diagnosis.

Loss is distinct from a slow response
A missing response is different from a returned response with high RTT. Keep packet loss visible: a latency chart that omits failed probes can make an unreliable connection look deceptively calm. SmokePing describes packet loss as potentially resulting from an overloaded device or a router configuration issue, among other possibilities; the graph alone does not establish the cause. SmokePing: Reading the Graphs
Probe type and vantage point define what the result means
An ICMP ping to a host, an HTTP request to a service, and a DNS lookup measure different exchanges. Likewise, a graph only records the route from the monitor’s location to its target. Label both details, and compare more than one target or measurement location when it helps distinguish a local change from one affecting a wider path.
Quick Recap
Troubleshoot a slowdown using the timeline
- Find the reported interval. In a timeline tool, focus on the period when the slowdown occurred rather than relying only on a current reading. PingPlotter lets you change or scroll its timeline window. PingPlotter: Timeline Graphs
- Compare targets and measurements. Check whether latency or loss changed for the gateway, an external target, or an application-level probe. A change affecting only one target does not by itself show that the home connection is at fault.
- Check probe reachability and policy. Confirm that the target accepts the selected probe and that local firewall or network policy does not block it. A missing ICMP reply may reflect filtering or host policy rather than a complete service outage; when user experience is the question, pair ICMP with a relevant application-level probe.
- Correlate, then investigate. Compare the timing with known workload or equipment changes. Treat a spike as evidence that measurements changed, not as a root-cause finding; intermediate-hop behavior alone is not enough to identify the source of a problem.
