May 2026 was a busy month for the monitoring and observability ecosystem. Rather than relaying each press release in isolation, we tried to read across them here at Sensor Factory: what’s really happening in the market? Three major themes emerge — growing rigor around LTS releases, strategic moves on the product and acquisition side, and agentic AI moving decisively into production.
Releases & LTS cycles: maturity sets in
On the Zabbix side, version 7.0.26 LTS shipped on May 5, followed by 7.4.10 on May 6. The 7.0 branch remains supported until June 30, 2029 — it’s the branch we recommend aligning new client deployments to. The 7.4 branch reaches end-of-support on September 30, 2026; clients running it should plan their migration to 7.6 (upcoming) or 8.0 (in alpha) before the fall.
Centreon also released maintenance updates: the monitoring agent 24.10.15 on May 5, and the monthly Monitoring Connectors release, which includes a new F5OS SNMP connector. Also worth noting is a security bulletin published on May 12 covering an SQL injection in the centreon-anomaly-detection component (CVSS 8.8, high severity) — fixes are provided for the 25.10.5 and 24.10.10 branches. If you’re running Anomaly Detection, this should be applied promptly.
At VictoriaMetrics, v1.136.9 LTS shipped on May 8 with a Go security upgrade (1.26.2 → 1.26.3) and fixes for vmagent / vmsingle. More interesting on the Kubernetes side: on May 20, the operator gained support for HPA for vmauth (Horizontal Pod Autoscaling). For multi-tenant clusters with variable load, this is a genuine operational improvement — the authentication proxy can now scale on demand without manual intervention.
On the M81 side, an IBM i partner, Control for i V4.01 is now available with compatibility for IBM i V7R3, V7R4, and V7R5. The 200+ plug-and-play checks continue to expand — useful for those of you still monitoring iSeries partitions via Zabbix, PRTG, Centreon, or Nagios.
Strategic moves
Paessler announced on May 6 the appointment of Mav Turner as Chief Product Officer. The background is notable: 15 years in network monitoring and observability, with stints at SolarWinds (10+ years) and then Kentik as CPO. His statement emphasizes two priorities — simplifying usage and using AI to shift from reactive to proactive. That’s consistent with what we see in the field: PRTG remains the leader in simple agentless monitoring, but Paessler has to prove it can absorb the AIOps wave to stay competitive against observability pure-players.
On the IP-Label / Ekara side, a reminder for anyone who missed the January news: the acquisition by ITRS is now finalized. Ekara remains operational and the product continues to evolve (RUM + synthetic + AI-driven triage), but the integration with the ITRS suite (Geneos, Capacity Planner) opens up possibilities for unified observability architectures. One to watch over the coming quarters.
Agentic AI enters production
This is probably the most striking theme of spring 2026: agentic AI is leaving the labs and entering the monitoring products themselves.
SolarWinds launched in April SW1, its “agentic AI teammate” — an agent that orchestrates operational workflows (incident triage, root-cause identification, remediation suggestions). Built on their proprietary Agentic Framework, SW1 operates as a governed AI identity that works alongside IT teams. Beyond the marketing, it’s one of the first large-scale deployments of AI agents in the traditional monitoring world, not just in next-generation tools.
New Relic, for its part, held its Advance 2026 event in May around the theme of Intelligent Observability: fewer dashboards to read, more signals interpreted and actions suggested by the system. Their AI Impact 2026 report highlights customer figures — a 25% reduction in MTTR on incidents handled by AI. Take that with the usual caution around vendor benchmarks, but the direction is clear. FutureStack May 25-27.
Mr Suricate is playing the same tune on the testing side: their new product Magui.ai, presented at NRF 2026, turns manual tasks into automated actions via AI. It’s the natural evolution of the platform — from no-code testing toward intelligent orchestration of synthetic monitoring scenarios.
Even Paessler explicitly states its intention to “increasingly use AI to help teams get ahead of issues” in the statement from its new CPO. The message is unanimous: 2026 is the year observability is expected to understand, not just collect.
Reading across the month
Three observations we take away from this month of May:
- LTS cadences are aligning. Zabbix 7.0 through 2029, VictoriaMetrics 1.136.x in active LTS, Centreon with 24.10 / 25.10 cycles now clearly defined. For clients who have to defend a multi-year plan to their leadership, that’s a good thing: vendors are finally delivering predictability.
- The ecosystem is industrializing. Executive appointments, strategic acquisitions (ITRS / IP-Label), proliferating integration layers (Kubernetes HPA, F5OS connectors, Control for i across 7 different tools)… we’re no longer in the “emergence” phase, but in the “operational maturity” phase.
- Agentic AI will change the game faster than expected. SW1, Intelligent Observability, Magui.ai: a year ago we were talking about AI agents in theory, and they’re reaching production in six months. The CIO question will soon no longer be “do we integrate AI into monitoring?” but “which scopes do we hand off to the agent, and with what governance?”. More on that in an upcoming article.
What we do with this at Sensor Factory
For our clients, these announcements directly guide our recommendations. We’re moving new Zabbix projects to 7.0 LTS. We’re documenting the Centreon Anomaly Detection fixes for affected clients. We’re evaluating HPA vmauth for multi-tenant VictoriaMetrics deployments. We’re tracking SW1 and Magui.ai to understand what they actually enable — not just what the vendors say about them.
If you have a point on your current stack worth digging into in light of these developments, let’s talk.
