24/7 IT Monitoring – Why is it worth monitoring your IT infrastructure around the clock?
The company's IT infrastructure operates 24/7 – servers send emails at night, databases handle customer queries in the morning, and backups run on weekends. But does your IT team also work 24/7? If not, problems can arise when no one is in the office – and then you have to wait until the morning for a solution. 24/7 IT infrastructure monitoring is a solution that keeps an eye on your infrastructure while everyone is asleep.
What is 24/7 IT monitoring?
24/7 monitoring means automatic tracking of all IT systems in your company around the clock – 365 days a year, regardless of weekends, holidays or night hours.
How it works:
- Monitoring tools collect data from all systems (servers, network, databases, applications)
- Data is analyzed for anomalies (high temperatures, decreased availability, attacks)
- If something is wrong, the system automatically sends an alert
- The alert goes to a human (engineer or someone in the SOC – Security Operations Center)
- A person analyzes the problem and intervenes
The difference between reactive and proactive monitoring
- Reactive Monitoring: "Ugh, the server died at 3 a.m., we're waiting until 8 a.m. for IT"
- 24/7 proactive monitoring: "At 2:47 a.m., the system detected a problem, an alert was sent to the service center, and at 3:15 a.m., the problem was resolved."
WHAT does IT infrastructure monitoring include?
Physical infrastructure:
- Server availability (whether they are alive or dead)
- Temperature in the server room (is it overheating)
- Power supply (whether the UPS is working or there is a power outage)
- Data carriers (disks – do they break down)
Network:
- Router and switch availability
- Network bandwidth (am I flooding anyone with data)
- Latency (is the connection lagging)
- Attacks (hack attempts, DDoS)
Applications and services:
- Is the mail server working?
- Does the database respond to queries?
- Is the business app available?
- Did the backup start and finish without errors?
IT security:
- Login attempts (is someone hacking?)
- Changes to systems (who changed what?)
- Threats (viruses, malware)
COST vs. BENEFIT – CALCULATOR
Scenario without 24/7 monitoring:
| Event | Frequency | Cost | Total |
| Server Downtime | 2x/year | 10,000 PLN/hour | 20,000 PLN |
| Data Leak (No Detection) | 1x/2 years | 50,000 PLN | 25,000 PLN |
| Ransomware Attack | 1x/3 years | 100,000 PLN | 33,000 PLN |
| Data Loss (No Backup) | 1x/5 years | 200,000 PLN | 40,000 PLN |
| TOTAL/YEAR | ~118,000 PLN |
Scenario with 24/7 monitoring:
| Item | Cost |
| Monitoring Tools | 2,000 – 5,000 PLN/month |
| 24/7 Monitoring Service (Online Support or other) | 3,000 – 8,000 PLN/month |
| Training | 2,000 PLN (one-time fee) |
| ~YEAR 60,000 – 156,000 PLN |
Examples of real benefits of IT monitoring:
Reduction of incidents: Most problems are caught before they become a crisis → savings of PLN 30,000 – 80,000/year
Faster response: Problem solved in 15 minutes instead of 4 hours of waiting → savings due to reduced business losses
Image protection: No publicly known data leaks → illegal
ROI (Return on Investment): Return on investment is achieved in 3-6 months
Verdict: 24/7 monitoring pays off.
TOP 5 incidents that can be prevented by monitoring the company's IT infrastructure:
| Incident | Without monitoring | With 24/7 monitoring |
| Server crashed at 2 AM | Detected at 8 AM (~6 hours of downtime) | Detected at 2:03 AM (3 minutes) |
| Disk full | Application crashes, data loss | Disk 80% full alert |
| Someone hacked | Detected after 2 months | Immediate notification |
| Backup failed | Detected on the Friday before the weekend | Notification the day before |
| DDoS attack | Network slowed for hours | Attacker blocked after 5 minutes |
Metrics that should be monitored:
Availability (Uptime):
- Target: 99.5% – 99.9% availability
- What does this mean: Max 1-4 hours of downtime per year
- Monitoring helps maintain this level
System Response Time (Response Time):
- Database < 500ms to a query
- Business application < 3 seconds
- Monitoring alerts when exceeded
Mean Time to Resolution (MTTR):
- Without monitoring: 4-8 hours
- With monitoring: 15-30 minutes
- Difference: Huge
Security Metrics:
- Number of intrusions per month (target: 0)
- Mean Time to Detect (MTTD): < 1 minute
- Number of security incidents
