ColoServe Server Monitoring Services:
ActiveAlert Monitoring & Server Component Monitoring
If your web site or Internet application goes down or experiences problems, do you want to be proactively notified? Do you require more visibility into the health of your server's CPU, hard disk space and memory utilization? ColoServe's Monitoring Services will send email notifications to you and your staff if any of your TCP/UDP ports fail to respond, or if your server's components reach predetermined thresholds, enabling you to better manage your hosting environment.
ActiveAlert Monitoring
ColoServe's ActiveAlert Monitoring will help you make sure your Internet-based services are always available. ColoServe will configure and monitor the availability of your server or services (up to 5 per IP) from an off-site location and alerts will be sent to any email addresses you would like (up to 5) if your server or services become unavailable.
Pricing
$19.99/mo (1 IP / 5 Services)
$99.99/setup
Need to monitor multiple IPs?
Every 5th ActiveAlert Monitoring package you purchase is free.
TCP/UDP Services List
The following are some common services (and their corresponding ports) that can be monitored with the ActiveAlert monitoring service to ensure that they are running and responding properly. The monthly price includes the monitoring of up to 5 services per IP address, with alerts being sent for up to 5 Email addresses.
| PORT | PROTOCOL | NAME |
|---|---|---|
| 20,21 | TCP/UDP | FTP |
| 22 | TCP | SSH |
| 23 | TCP | Telnet |
| 25 | TCP | SMTP |
| 53 | TCP/UDP | DNS |
| 80 | TCP | HTTP |
| 110 | TCP | POP3 |
| 113 | TCP/UDP | Ident |
| 123 | UDP | NTP |
| 143 | TCP | IMAP |
| 389 | TCP/UDP | LDAP |
| 443 | TCP | HTTPS |
| 1433 | TCP | MSSQL |

Server Component Monitoring
ColoServe's Server Component Monitoring can that ensure that your server is running at peak performance. ColoServe will set predetermined thresholds for your CPU, Disk and Memory, and if any of the thresholds are reached, alerts will be sent to any email addresses you would like (up to 5). Server Component Monitoring therefore empowers you to make more qualified decisions about your Internet hosting environment, as well as being alerted to any potential performance degrading situations before they occur.

The following are the thresholds that ColoServe recommends for the Server Component Monitoring service, though thresholds can be set at any particular level that you wish (some applications may make different thresholds preferable).
CPU (Processor) Utilization
Windows Recommended Threshold: 90%
The CPU utilization percentage is historically the metric used to measure the performance of a Windows-based server. This metric is linear, and is a function of the load on your server. Our threshold of 90% indicates that an alert will be sent out when your server sustains a CPU utilization of 90% or higher, implying that the server will only be able to facilitate a small amount of new users and/or processes before the CPU is maxed out and starts swapping data to disk, which drastically decreases performance.
Linux/Unix Recommended Threshold: 10
The server load average is historically the metric used to measure Linux and UNIX server performance. The load average is more representative of the server performance due to the way Linux and UNIX kernels schedule CPU requests. The Linux/UNIX architecture generates very high CPU utilization (close to 100%) for relatively short periods of time, as opposed to having an CPU utilization percentage that increases in a linear fashion. The load average is a numeric result generated as a function of the number of processes queued and the number of processes receiving CPU time. At any one time, there are a minimum of THREE load averages for a Linux or UNIX system; 1, 5, and 15 minute values. Our threshold of 10 would mean that you would be alerted when your server consistently maintains a ratio of 10 or more processes queued to every process running in CPU.
Disk Utilization
Windows and Linux/Unix Recommended Thresholds: 95%
The percentage of free space available on your server's drive is an extremely important factor in minimizing downtime. While most modern operating platforms will reserve a certain percentage of disk space for administrative use, most Internet facing services will shut down without available space. Our threshold of 95% would mean that alerts will be sent out when your server is down to its last 5% of available disk space.
Memory Utilization
Windows Recommended Threshold: 50 MB available
Memory utilization in Windows is also linear, and is strictly a function of the load on the processes and services running on your server. The Windows resource allocation model de-allocates, or frees up, memory that is no longer required by a process or service. If Windows runs out of free memory, the server will begin thrashing (consecutive read and write operations to a pagefile), and stability becomes extremely compromised. Our threshold of 50 MB means that you will be alerted when there is 50 megabytes or less of available physical memory for a sustained period of time.
Linux/Unix Recommended Threshold: 5 MB available
Memory usage for Linux and UNIX servers exhibit different characteristics than that of Windows. Linux and UNIX tend to allocate all (except a small amount for administration) available memory, rather than allocating the requested resources at execution time. The result is that for Linux and UNIX servers, memory usage only becomes a problem when there is approximately 5 megabytes or less of available, unallocated memory. Our threshold of 5mb means that you will be alerted when your server has less than 5 megabytes of unallocated, available memory, which indicates a system that is under extremely heavy load and/or utilization.
