The problem
What happens if you just have FlexLM's built-in tools
FlexLM (Flexera’s FlexNet Publisher) tells you what’s checked out right now — if you know where to look. It doesn’t tell you what happened at 2 a.m. last Tuesday, which team is quietly hoarding seats, or how close you are to the next denial before it happens.
That gap surfaces at the worst possible time: mid-renewal, when a vendor presents a usage report you can’t independently verify, or mid-audit, when you’re asked to reconstruct months of usage from memory and scattered logs.

Idle sessions
A checked-out seat sitting untouched still counts against your pool. Without history you can’t distinguish “in use” from “checked out three days ago and forgotten.”
Denial-driven over-buying
Denial spikes often trace to idle sessions blocking the pool — not genuine demand. You can’t tell which until you have usage history.
Peak-demand purchasing
40
idle seats reclaimed
A 200-seat pool showing 1100+ checked out looks like a case for buying capacity. Usage history often tells another story — 40 seats open for days without a single active operation. Reclaiming them through license harvesting can close the entire apparent gap without a single new license purchase.
License managers
Tracked by
FlexLM isn’t the only concurrent license manager in engineering software,
and the differences affect what monitoring can surface.
FlexLM
FlexNet Publisher by Flexera
Second
The most widely deployed license manager in engineering software. OpenLM gives you the finest-grained view available.
RLM
Reprise License Manager
Second
A lighter-weight alternative some vendors use instead of FlexLM. The monitoring experience stays consistent even if the underlying daemon isn’t.
DSLS
Dassault Systèmes License Server
Minute
Used across CATIA, SIMULIA, DELMIA (incl. DSLS Cloud). Still enough resolution to catch idle sessions and overuse patterns.

Who it's for
Built for multi-site and hybrid engineering teams
The organizations that feel FlexLM’s visibility gap most acutely aren’t running one license manager in one office. They’re running FlexLM for one vendor’s tools, DSLS for their Dassault portfolio, and possibly RLM somewhere in the mix — spread across engineering teams in different time zones.
A denial in Singapore at 2 a.m. doesn’t get noticed until someone in Houston checks a report hours later. Centralizing FlexLM, RLM, and DSLS monitoring into one console doesn’t just save admin time — it closes the exact visibility gap a distributed organization is most likely to have.
Visibility gaps
Common FlexLM monitoring gaps —
and how to close them
Options file complexity
Files control who gets access to what, but they’re easy to misconfigure. Options file management gives you a managed approach instead of an honor system.
No alerting on denials
If nobody finds out about a denial until the engineer complains, you’ve already lost productivity. Configurable alerts for overuse, denials, and expiring files close that gap.
Remote service management
Restarting a FlexLM service often means someone physically at the server, or a slow ticket to IT. Remote management collapses that into a console action.
No single hybrid view
Multi-site organizations frequently run FlexLM in one region, DSLS in another, RLM elsewhere — each with its own login and quirks.
Manual, ad hoc reporting
When reporting means exporting lmstat output into a spreadsheet on request, it happens rarely and only after a problem has already occurred — never as a practice that catches problems early.
Getting started
What to expect in the first 30 days
Day 1
Connect
OpenLM connects to your FlexLM, RLM, or DSLS servers and starts collecting usage history immediately — it reads data those servers already generate.
Week 1–2
Patterns surface
Which sessions sit idle longest, which pools see denial spikes, and at what times — the shape of your real usage starts to emerge.OpenLM connects to your FlexLM, RLM, or DSLS servers and starts collecting usage history immediately — it reads data those servers already generate.
Day 30
Decide
Most teams have enough history to act: which idle sessions to reclaim, which pools are under-provisioned, and where a renewal conversation shifts from “how many seats last year” to “here’s what we actually used.”
Proven results
What real-time monitoring found at Baker Hughes
Baker Hughes used OpenLM to monitor its ANSYS Mechanical pool over a 30-day trial. The team owned 79 seats, but ANSYS granted a temporary pool of up to 500 to gauge real demand.
Usage peaked at 155 concurrent seats — buying for that peak would have cost an estimated $2.7 million. Usage data let the team identify idle sessions, dropping peak usage to 90–100 seats over the following weeks.

Differentiation
Vs. spreadsheets & vendor consoles
The alternative usually isn’t another platform — it’s a spreadsheet, a handful of lmstat outputs pasted into email, or checking each vendor console one at a time. That works until your pool grows past a handful of applications.
Generic SAM tools treat FlexLM as one line item among thousands of desktop apps — shallow reporting that wasn’t built for how concurrent engineering licenses behave. OpenLM started from the license manager itself, then extended into full software asset management.
Day-to-day
What changes for the license admin
Instead of pulling an lmstat snapshot when someone complains about a denial, you open a dashboard that already shows the denial, when it happened, and what else was checked out at the time.
Alerts take over the job of noticing a problem, so your time shifts from watching for issues to deciding what to do about the ones the system already flagged.
FAQ
Frequently asked questions
FlexLM (Flexera’s FlexNet Publisher) is a concurrent, floating-license system: a shared pool of seats that any authorized user can check out and release. Unlike a named-user license, there’s no fixed one-to-one mapping between a person and a seat, so you need continuous usage tracking — not a one-time audit — to see who’s really using what.
All three are concurrent license managers used across engineering software, but they’re built by different vendors with different tracking granularity. OpenLM monitors FlexLM and RLM by the second, and DSLS by the minute, giving you a consistent view across all three from one console.
OpenLM doesn’t replace FlexLM’s own daemons — it monitors what they’re doing continuously. Instead of a one-time snapshot, you get historical usage graphs, denial tracking, idle-session alerts, and remote management layered on top of your existing FlexLM infrastructure.
Yes, OpenLM can support 100+ engineering license managers, including FlexLM, RLM, DSLS, and more, all from a single console.
License harvesting automatically identifies and reclaims idle FlexLM sessions, returning unused seats to the pool instead of leaving them checked out indefinitely. It’s one of the fastest ways to close the gap between what you own and what you actually need to buy.
Most organizations see usage data within the same day the connection is configured, since OpenLM interfaces directly with your existing FlexLM, RLM, or DSLS servers rather than requiring a separate agent rollout across every workstation.
No. OpenLM reads usage, denial, and log data from your existing servers without sitting in the license checkout path, so entitlement enforcement works exactly as it did before.
Yes. Continuous usage history gives you a records-based answer to how licenses were actually used over any period an auditor asks about, instead of a scramble to reconstruct usage from memory or scattered logs.
