The Cacti Expert on Call When You Need One

Cacti is powerful — and technically demanding. When your poller slows down, graphs stop rendering, or an upgrade goes wrong at 22:00 on a Friday, you need someone who knows the platform deeply, not someone reading documentation for the first time.

Urban-Software.de provides dedicated Cacti support under a monthly retainer model. You get a fixed block of hours, a guaranteed response SLA, and direct access to Thomas Urban — the developer behind the Cereus plugin ecosystem and an active contributor to the Cacti community.

No ticketing queues. No junior staff. No offshore handoffs. You get the person who wrote the plugins you’re running.

What clients typically contact us for:

  • Poller performance degradation at scale
  • Cacti version upgrades (1.2.x → 1.3.x)
  • RRD file corruption and data recovery
  • Custom SNMP data source templates
  • Plugin installation, configuration, and debugging
  • MySQL InnoDB tuning for large installations
  • Backup strategy and disaster recovery planning
  • Staff training and knowledge transfer

Why Urban-Software.de

Cacti-Exclusive Expertise

No generalists. Urban-Software.de works exclusively with Cacti. Deep source-level knowledge, active plugin development, and a community presence that is verifiable at github.com/thurban and forums.cacti.net.

Written SLA Commitment

Response time commitments in writing — not “we’ll get back to you”. SLAs range from 48 hours (Starter) to 6 hours (Enterprise), measured from ticket receipt within the availability window.

German Vendor

German-language support available. German invoicing with proper VAT handling. GDPR-compliant practices. A verifiable legal entity (VAT-ID: DE301912908) — not an anonymous online profile.

Direct Access

You always work with Thomas Urban directly. No account managers, no escalation chains, no junior engineers learning on your production system.

Transparent Hour Tracking

Monthly hour log attached to every invoice. You always know how many hours were used, what they were used for, and how many remain. No billing surprises.

Plugin Developer Advantage

The Cereus plugin ecosystem — IPAM, multi-channel alerting, REST API, data export, Grafana integration — means you get support from the person who built the tools, not someone reading the docs.

All tiers include direct access to Thomas Urban. All prices exclude VAT. Support is provided during evening and weekend hours (Mon–Fri from 17:00 CET/CEST; Sat–Sun all day).

Who We Work With

ISPs & Telecoms

Running Cacti to monitor hundreds or thousands of interfaces. Typical need: upgrade path clarity, poller performance at scale, SNMP template gaps.

MSPs & NOC Teams

Need a Cacti specialist to escalate to or sub-contract monitoring work. White-label retainer arrangements available.

Enterprise IT & Universities

Internal Cacti installation set up years ago. Original admin has left. Nobody on the team has the depth to maintain and evolve it confidently.

Frequently Asked Questions

When are you available?

Support is provided Monday–Friday from 17:00 CET/CEST, and Saturday–Sunday all day. This reflects my availability outside of a separate full-time professional commitment. Daytime emergency intervention (09:00–17:00 CET/CEST) is available on request at +50% surcharge (€225/h).

Do unused retainer hours roll over?

No. Unused hours in a given month do not roll over. The monthly fee represents the cost of guaranteed availability — whether or not all hours are used. This is standard practice for dedicated support retainers.

Can I start with a project and move to a retainer later?

Yes. Many clients start with a fixed-price project (e.g. a Cacti upgrade or performance overhaul) and transition to a retainer for ongoing support once the initial work is complete.

Do you support Cacti versions older than 1.2.x?

Yes, though I will typically recommend a migration path to a supported version. Legacy 0.8.x installations can be assessed on request.

Can you help with Cacti plugins not developed by Urban-Software.de?

Yes. Third-party plugins (Thold, Weathermap, Syslog, Monitor, etc.) are within scope. Custom and in-house plugins can also be reviewed and debugged.

Do you sign NDAs and MSAs?

Yes. A standard NDA and Master Services Agreement are available and can be signed before any access is provisioned. Your environment details remain confidential.

Is support available in German?

Yes. Communication can be in German or English — your preference.
