Resource Utilization Basics

Think of IT resource management like keeping tabs on your phone's battery life. You need to track CPU, memory, storage, and network usage to keep everything running smoothly.

Here's what the numbers should look like:

Area	Target Range	Warning Signs
CPU Usage	60-80%	Constant spikes above 90%
Memory	70-85%	Frequent page faults
Storage	65-75%	Less than 15% free space
Network	50-70%	Packet loss, high latency

When it comes to performance, your usage levels make all the difference:

Usage Level	Impact on Performance	Business Effect
Below 50%	Wasted capacity	Higher costs
70-80%	Best performance	Good value
Above 90%	Slow response times	Lost productivity

But here's the thing:

You can run into problems if you don't balance your resources right:

Problem	Cause	Effect
Overutilization	Running too many workloads	System crashes, slow response
Underutilization	Poor capacity planning	Money wasted on idle resources
Uneven Usage	Bad workload distribution	Some systems overloaded while others sit idle

The folks at Infinum found that different roles need different resource levels:

Directors: 33% utilization
Senior staff: 63% utilization
Mid-level: 74% utilization
Junior staff: 75% utilization

"Our business decisions are never made on an inner feeling or intuition. Productive gives you answers to questions like what's the profit, how much are the expenses, what's the projected revenue, what's the utilization?" - Ervin Jagatić, Head of Client Services at Infinum

Bottom line: Aim for 70-90% resource usage. It's the sweet spot where you get the best bang for your buck. Keep an eye on those numbers and fix small issues before they turn into big headaches.

10 Key Resource Metrics

Here are the must-track metrics for your IT resources:

1. CPU Usage

Your CPU numbers tell you if your processors are getting overworked:

Metric	Normal Range	Warning Signs
Load Average	0.7 - 2.0	Above 3.0 for extended periods
User Time	65-80%	Above 90%
System Time	10-20%	Above 30%
I/O Wait	5-10%	Above 20%

2. Memory Stats

Memory problems = system crashes. Keep an eye on these:

Memory Metric	What It Means	Target Range
Used Memory	Active RAM usage	70-85%
Page Faults	Memory retrieval errors	Under 1000/min
Swap Usage	Virtual memory use	Under 20%
Cache Hit Rate	Memory access speed	Above 90%

3. Storage Metrics

Bad storage = slow everything. Here's what to watch:

Storage Metric	Target	Impact

Latency	10-20ms (HDD), 1-2ms (SSD)	Response time
Free Space	25-35% minimum	System stability
Read/Write Ratio	80/20 typical	Load balance

4. Network Usage

Your network can make or break performance:

Network Metric	Good	Bad
Bandwidth Use	50-70%	Above 85%
Packet Loss	Under 1%	Above 2%
Latency	Under 100ms	Above 300ms
Error Rate	Under 0.1%	Above 0.5%

5. Response Times

Users hate waiting. Period.

Response Type	Target Time	Max Acceptable
Time to First Byte	Under 200ms	500ms
Page Load	Under 1s	3s
API Response	Under 300ms	1s
Database Query	Under 100ms	500ms

Most big systems handle about 2,000 requests every second. Wait more than a second? Your users are already thinking about leaving.

Tools like eyer.ai help you track these metrics in real-time. They work with Telegraf and Prometheus to spot problems before your users do.

Tracking Tools

Here's how modern monitoring tools help you catch and fix problems before your users notice them:

Eyer.ai Monitoring

Eyer.ai connects with your data sources to track what matters:

Setting Usage Limits

Your system needs breathing room. Here's what to aim for:

Resource Type	Target Limit	Why It Matters
CPU	70-80% max	Room for traffic spikes
Memory	85% RAM	Keeps things snappy
Storage	80% space	Maintains speed
Network	60% bandwidth	Handles sudden surges

Auto-Scaling Setup

Let your system grow (or shrink) based on what it needs:

Scaling Type	Works Best For	How It Works
Vertical	Single servers	Boost CPU/RAM
Horizontal	Distributed apps	More/fewer servers
Time-based	Regular patterns	Set schedules
Load-based	Random spikes	Follow the metrics

Planning for Growth

Keep an eye on these numbers:
