Solved: Getting priced out of Solarwinds

#devops #programming #tutorial #cloud

🚀 Executive Summary

TL;DR: SolarWinds users often face escalating licensing costs and vendor lock-in, leading to critical monitoring failures when element limits are reached. This article outlines strategies to break free, including immediate cost reduction through a ‘monitoring diet’ and a permanent migration to open-source observability stacks like Prometheus and Grafana.

🎯 Key Takeaways

Implement a ‘Monitoring Diet’ by aggressively unenrolling non-production-critical or decommissioned devices from SolarWinds, potentially using the SWIS API, to reclaim licenses and reduce immediate costs.
Migrate to a ‘Prometheus & Grafana’ stack for programmatic observability, shifting from SNMP pull-based monitoring to applications exposing metrics endpoints scraped by Prometheus, with visualization in Grafana and alerting via Alertmanager.
Adopt a ‘Nuclear Option’ hybrid approach where SolarWinds is retained only for bare-minimum, non-negotiable devices (e.g., compliance, esoteric hardware), while the majority of infrastructure is moved to an open-source stack to drastically reduce licensing tiers.

So, You’re Getting Priced Out of SolarWinds? Been There, Done That.

I remember it like it was yesterday. 2:17 AM. My phone is lighting up the room, screaming with PagerDuty alerts. The primary database cluster, prod-db-01, is offline. But here’s the kicker: all our dashboards are green. SolarWinds says everything is fine. We spent the next 45 minutes flying blind, trying to figure out what was happening, only to discover later that our SolarWinds license had hit its element limit two days prior and had quietly stopped polling our most critical infrastructure. We were paying a fortune for a tool that failed us when we needed it most because of a licensing bean counter. That was the day I said, “Never again.”

The “Why”: Understanding the Vendor Lock-In Trap

Let’s be real. This isn’t an accident; it’s a business model. Large, all-in-one monitoring suites like SolarWinds are designed to become the central nervous system of your IT operations. They get you in the door with a reasonable starting price, their agents and polling engines spread across your network like ivy, and before you know it, ripping them out feels like performing open-heart surgery on your entire infrastructure. The pricing model—often based on nodes, elements, or interfaces—is designed to grow exponentially with your company. Every new VM, every switch, every container you spin up adds to the tab. The renewal comes, the price has jumped 30%, and you feel like you have no choice but to pay up. But you do have a choice.

Solution 1: The Quick Fix (The “Monitoring Diet”)

This is your immediate, get-out-of-jail-free card to get back under your license limit and stop the bleeding. It’s not a permanent solution, but it buys you breathing room. The goal is to be absolutely ruthless about what you’re monitoring.

Ask your team these questions:

Do we really need to monitor every single virtual interface on our dev-k8s-worker-nodes?
Are we polling non-critical staging servers at the same frequency as production?
Are there decommissioned devices still taking up licenses? (You’d be surprised.)

We once reclaimed nearly 20% of our licenses just by running a discovery and aggressively unenrolling anything that wasn’t production-critical or directly supporting it. You can even use the SolarWinds API to script some of this. Here’s a conceptual PowerShell snippet of what that might look like to find nodes that haven’t been heard from in a while:

# NOTE: This is a conceptual example. You'll need the Swis PowerShell module.
# Connect to your SolarWinds Information Service (SWIS)
$swis = Connect-Swis -Hostname "solarwinds.yourcompany.com" -Username "api_user" -Password "your_password"

# Define "stale" as not seen in 30 days
$staleDate = (Get-Date).AddDays(-30)

# Query for nodes that haven't been polled recently
$staleNodesQuery = "SELECT Caption, NodeID, LastSync FROM Orion.Nodes WHERE LastSync < @staleDate"
$staleNodes = Get-SwisData $swis $staleNodesQuery @{ staleDate = $staleDate }

# Now you have a list to investigate and potentially unmanage/delete
$staleNodes | Format-Table

Warning: Be careful with this. Double-check that a “stale” node isn’t just a critical, low-traffic server that’s being polled infrequently. Always verify before you delete.

Solution 2: The Permanent Fix (The “Prometheus & Grafana” Migration)

This is the real solution. It’s about changing your philosophy from “point-and-click monitoring” to “programmatic observability.” The most common stack for this is Prometheus for time-series data collection and Grafana for visualization. This is what we ultimately did.

It’s not a simple drop-in replacement. It requires a different mindset. Instead of the monitoring tool “pulling” data with SNMP, your applications and servers “expose” a metrics endpoint, which Prometheus then “scrapes.”

Here’s a look at what a basic Prometheus configuration looks like to start scraping metrics from your own nodes:

# prometheus.yml
global:
  scrape_interval: 15s # By default, scrape targets every 15 seconds.

scrape_configs:
  - job_name: 'node_exporter'
    # Scrape metrics from Linux servers running the node_exporter agent
    static_configs:
      - targets: ['prod-web-01:9100', 'prod-web-02:9100', 'prod-db-01:9100']

  - job_name: 'windows_exporter'
    # Scrape metrics from Windows servers running windows_exporter
    static_configs:
      - targets: ['prod-ad-01:9182', 'prod-fileshare-01:9182']

The beauty here is that the cost is based on your infrastructure (CPU, RAM, disk for the monitoring servers), not on how many devices you monitor. It scales with you, not against you.

Tool	Role in the Stack
Prometheus	The core engine. It scrapes and stores time-series metrics. It handles the alerting logic.
Grafana	The dashboard. It queries Prometheus (and many other sources) to build beautiful, shareable dashboards.
Alertmanager	Handles alert routing, deduplication, and notification to services like PagerDuty, Slack, or email.
Exporters	These are the “agents.” Small services you run on your hosts (like `node\_exporter` for Linux, `windows\_exporter` for Windows) that expose the hardware and OS metrics.

Pro Tip: Don’t try to boil the ocean. Start your migration with a single, non-critical service. Get your feet wet, build your first Grafana dashboard, set up one alert. Learn the process, then expand. Our first target was our internal CI/CD cluster.

Solution 3: The ‘Nuclear’ Option (Starve The Beast)

Sometimes, you can’t get rid of SolarWinds completely. Maybe you have a compliance requirement, a specific piece of esoteric hardware that only it can monitor well (I’m looking at you, legacy-cisco-asa-5525), or internal political capital is just too low for a full rip-and-replace.

In this scenario, you adopt a hybrid approach. The goal is to make your SolarWinds instance as small and cheap as possible. You migrate 90% of your infrastructure—all your Linux/Windows servers, your cloud VMs, your container platforms—over to your new open-source stack. This dramatically reduces your node/element count.

You then leave SolarWinds in place to monitor only the bare-minimum, non-negotiable devices. When the renewal conversation comes up, you’re in a position of power. You’re not asking for a discount; you’re telling them you want to downgrade to their smallest license tier because you’ve offloaded the majority of the work. This turns a multi-hundred-thousand-dollar renewal into a much more palatable number, and you’ve already built its replacement for everything else.

It’s a tough road, but getting out from under a punitive licensing model is one of the most liberating things you can do for your team and your company’s budget. You stop spending time managing a tool and start spending time building true observability. Good luck.
