Last9 vs SolarWinds: In-Depth Comparison 2026

Last9 and SolarWinds serve fundamentally different operational models. Last9 is a Prometheus-as-a-Service platform designed to simplify metric storage, querying, and alerting for teams already invested in the Prometheus ecosystem. SolarWinds is a legacy enterprise network and infrastructure monitoring suite built before cloud native architectures existed, with separate modules for network performance, server health, and application monitoring.

Last9 builds on that foundation, while SolarWinds requires learning proprietary interfaces and query languages that do not translate to other tools.

This comparison covers pricing transparency, deployment model, alerting depth, observability breadth, and migration effort. It also includes CubeAPM as a third option for teams that need full stack observability with data residency and predictable cost.

Last9 Overview

Last9 is a managed Prometheus platform that handles metric storage, aggregation, and querying so teams do not have to operate their own Prometheus or Thanos clusters. It is designed specifically for engineering teams that have already standardized on Prometheus and need a vendor to manage the backend complexity.

Key features:

• Prometheus remote write compatibility
• Managed metric storage with high availability
• PromQL query interface
• Alerting with routing to Slack, PagerDuty, and other channels
• Grafana integration via Prometheus data source

What Last9 does not cover:

• Logs (you need a separate log management tool)
• Distributed tracing (no APM)
• Infrastructure dashboards beyond Prometheus exporters
• Real user monitoring or synthetics

Pricing:

Last9 pricing starts at $200/month for 1 million active time series with 13 months retention, and scales based on series count. For a mid-market team running 5 million active series, costs land around $800 to $1,000/month. High-cardinality workloads (like Kubernetes with pod-level labels) can push series counts into the tens of millions, where pricing becomes custom.

SolarWinds Overview

SolarWinds is an enterprise monitoring platform that launched in the early 2000s as a network performance monitor. It has since expanded into server monitoring (SAM), application performance monitoring (APM), database monitoring, and log analysis through separate modules that each require their own license.

Key features:

• Network Performance Monitor (NPM) for SNMP, NetFlow, and device health
• Server and Application Monitor (SAM) for Windows/Linux server metrics
• Database Performance Analyzer (DPA) for SQL query analysis
• AppOptics APM for distributed tracing (acquired and rebranded)
• Log Analyzer for centralized log collection

What SolarWinds does well:

• Deep network visibility with SNMP polling and topology mapping
• Strong Windows Server and Active Directory monitoring
• Pre-built dashboards for traditional enterprise infrastructure

What SolarWinds struggles with:

• High renewal costs documented by users on r/sysadmin, with one team reporting a 700% price increase at renewal
• Separate modules mean multiple UIs, separate data silos, and additive licensing costs
• Cloud native blind spots: Kubernetes, container, and microservices monitoring require bolt-on integrations
• Outdated UI and slow query performance cited in G2 reviews

Pricing:

SolarWinds pricing is module-based and scales by node count. Network Performance Monitor starts at $2,995/year for 100 elements. Server and Application Monitor starts at $2,895/year for 150 nodes. APM pricing is custom and typically quoted per application or transaction volume. A mid-market deployment monitoring 200 nodes across network, server, and application layers costs $15,000 to $25,000/year before support contracts.

This estimate models a production setup with network, server, and application monitoring across multiple modules. Smaller deployments or single-module usage will cost significantly less.

Feature-by-Feature Comparison

Metrics and Time Series Storage

Last9 is built entirely around Prometheus. You configure remote write endpoints in your Prometheus instances, and Last9 handles ingestion, storage, downsampling, and query federation. It supports high-cardinality labels and long-term retention without the operational burden of running Thanos or Cortex yourself.

SolarWinds collects metrics via polling (SNMP, WMI, API scrapers) rather than remote write. Each module has its own metric store. NPM tracks interface counters and latency. SAM tracks CPU, memory, and disk. There is no unified time series database across modules, so correlating network and application metrics requires exporting data to a separate analytics platform.

Verdict: Last9 wins for teams already using Prometheus. SolarWinds works for traditional enterprise monitoring but lacks the flexibility of a modern time series database.

Distributed Tracing and APM

Last9 does not offer distributed tracing. If you need trace data, you must use a separate APM tool like Jaeger, Tempo, or a commercial platform.

SolarWinds APM (formerly AppOptics) provides distributed tracing for applications, but it is a separate product with separate pricing. It supports language-specific agents for Java, .NET, Node.js, Python, and Ruby. However, users report trace sampling limits and gaps in microservices visibility compared to native OpenTelemetry platforms.

Verdict: Neither platform is strong here. If APM is a priority, consider a full stack observability tool instead.

Log Management

Last9 does not manage logs. You need to run a separate log aggregation tool like Loki, Elasticsearch, or a SaaS log platform.

SolarWinds Log Analyzer collects logs via syslog, file tailing, and Windows Event Log integrations. It provides keyword search and basic correlation with infrastructure events. However, it lacks full-text indexing speed and the correlation depth of modern log platforms.

Verdict: Both platforms require a separate log solution for serious log analysis.

Alerting and Incident Response

Last9 uses Prometheus alerting rules and supports routing to Slack, PagerDuty, Opsgenie, and webhooks. You write PromQL expressions for thresholds and rate-of-change conditions. Alerts fire based on time series data only, there is no correlation with logs or traces.

SolarWinds alerting is threshold-based with network-specific triggers like interface down, high bandwidth utilization, or node unreachable. Alerts route via email, SNMP traps, or third-party integrations. The alerting UI is module-specific, so setting up a cross-layer alert (e.g., high database load + network congestion) requires custom scripting.

Verdict: Last9 offers cleaner alerting for metric-driven workflows. SolarWinds covers more signal types (SNMP, WMI, logs) but lacks modern incident management integration.

Kubernetes and Container Monitoring

Last9 integrates with Kubernetes via Prometheus scraping of kube-state-metrics, node exporters, and cAdvisor. It stores pod-level metrics and supports high-cardinality labels like pod name, namespace, and deployment. However, you must configure Prometheus service discovery and exporters yourself.

SolarWinds has limited native Kubernetes support. You can monitor Kubernetes nodes as Linux servers in SAM, but pod-level visibility requires custom integrations or third-party exporters. SolarWinds does not map Kubernetes topology or correlate pod restarts with application errors.

Verdict: Last9 is the better choice for Kubernetes environments. SolarWinds is built for traditional infrastructure and lacks cloud native depth.

Data Residency and Compliance

Last9 is SaaS only. Metric data is sent to Last9’s cloud. For teams with data residency requirements (HIPAA, GDPR, or financial services), this is a non-starter.

SolarWinds offers on-prem deployment for all modules, giving full control over where telemetry data lives. This is one of SolarWinds’ few remaining advantages in 2026.

Verdict: SolarWinds wins for regulated industries that require on-prem deployment.

Pricing Comparison

Pricing estimates below model a mid-market team with 200 monitored entities (hosts, containers, network devices) generating approximately 5 million active Prometheus time series and 10 TB of log data per month.

Cost driver	Last9	SolarWinds	CubeAPM
Metrics storage	$800/month (5M series)	Included in module licenses	$0 (no per-series charges)
Logs	Not supported (separate tool needed)	Log Analyzer: $5,000/year	$1,500/month (10 TB × $0.15/GB)
APM/tracing	Not supported (separate tool needed)	AppOptics APM: custom pricing	Included in $0.15/GB
Network monitoring	Not supported	NPM: $2,995/year	Included
Infrastructure monitoring	Via Prometheus exporters	SAM: $2,895/year	Included
User seats	Unlimited	Per Orion seat: $2,895/year	Unlimited
Total monthly cost	~$800 (metrics only, excludes logs and APM)	~$1,700/month ($20,000/year across modules)	~$1,500/month (all signals)

Pricing based on publicly available information as of April 2026. Enterprise discounts, custom contracts, and negotiated rates are not reflected here.

Key takeaway: Last9 is affordable if you only need Prometheus metrics and already have separate tools for logs and traces. SolarWinds delivers network monitoring depth but stacks module costs quickly. CubeAPM offers the lowest total cost for unified observability when logs, traces, and metrics are all in scope.

Who Should Choose Each Tool

Choose Last9 if:

• Your team has standardized on Prometheus and PromQL
• You need managed Prometheus without operating Thanos or Cortex
• Metrics-only observability is sufficient (you already have log and trace tools)
• You are comfortable with SaaS and do not have data residency requirements
• Budget is under $1,000/month for metric storage

Choose SolarWinds if:

• Your infrastructure is majority on-prem with legacy network gear
• You need deep SNMP, NetFlow, and Active Directory monitoring
• Your team already knows SolarWinds and has multi-year contracts in place
• Data residency or air-gapped deployments are mandatory
• You have budget for $20,000+ annual licensing across modules

Choose CubeAPM if:

• You need unified logs, traces, metrics, and infrastructure monitoring
• Data residency or HIPAA/GDPR compliance requires self-hosted deployment
• You want predictable $0.15/GB pricing with no user seat fees
• Your stack is cloud native (Kubernetes, microservices, OpenTelemetry)
• You want to migrate off New Relic, Datadog, or Dynatrace without SaaS lock-in

Last9 vs SolarWinds vs CubeAPM: Three-Way Comparison

For teams evaluating both Last9 and SolarWinds, adding CubeAPM to the comparison clarifies where each tool fits.

Last9 solves one problem well: managed Prometheus storage. It does not replace a full observability stack. You still need separate tools for logs, traces, and infrastructure dashboards.

SolarWinds covers network and server monitoring deeply but uses outdated architecture that does not fit cloud native workflows. Module costs add up quickly, and the UI feels dated compared to modern platforms.

CubeAPM delivers full stack observability (metrics, logs, traces, infrastructure, Kubernetes, RUM, synthetics) in one self-hosted platform. It runs inside your VPC, so there are no data egress costs or compliance concerns. Pricing is $0.15/GB for all ingested data, with unlimited users and retention.

	Last9	SolarWinds	CubeAPM
Signal coverage	Metrics only	Network, infra, apps (separate modules)	Full MELT in one platform
Deployment	SaaS only	On-prem or SaaS	Self-hosted (vendor-managed)
Pricing model	Per active series	Per module, per node	$0.15/GB ingestion
OTel-native?	Partial	Partial	Native
Best use case	Managed Prometheus backend	Legacy enterprise networks	Unified cloud native observability

Verdict

Last9 and SolarWinds do not compete directly. Last9 is a metrics-only platform for Prometheus users. SolarWinds is a network-first monitoring suite for traditional enterprise infrastructure.

If you need managed Prometheus and nothing else, Last9 is the simplest option. If you operate legacy networks with SNMP devices and on-prem servers, SolarWinds has the deepest coverage despite its aging UI and high cost.

For teams building cloud native infrastructure who need logs, traces, metrics, and Kubernetes monitoring in one platform, CubeAPM delivers the most complete solution at the lowest total cost. It runs inside your infrastructure, supports OpenTelemetry natively, and scales to production workloads without unpredictable SaaS bills or data egress fees.
