Monitoring

Components monitored for Managed RHEL

The following components are monitored for Swisscom RHEL VM:

Component	Metric
Workload VM	Availability
Mountpoint /	Usage
Mountpoint /boot	Usage
Mountpoint /var	Usage
Mountpoint /var/log	Usage
Mountpoint /var/log/audit	Usage
Mountpoint /opt	Usage
Mountpoint /usr/local	Usage
Mountpoint /tmp	Usage
Mountpoint /opt/ds_agent	Usage

Alarming

If one of the defined threshold values is exceeded, an alert is sent to the Swisscom operation team. With the Managed RHEL service, no alerts are sent to you or the VM owner.

Logging

All relevant events to operation are collected centrally. Examples are given below:

Events:

• Rebooting the system
• Critical exceedance of threshold values

Metrics:

• VM availability
• File system load
• CPU load
• Memory Utilization

Thresholds are defined for these metrics (see chapter Monitoring above), which trigger an alarm if the respective metric is exceeded. Operating System logs and metrics are stored centrally. These logs are delivered via log forwarding, metrics are collected at 5 minute intervals.

Properties	Description
Restrictions and rules	All log and metering data are assigned to a unique CI.
The retention period of the metering raw data is 6 months while the VM exists. This raw data is also deleted 15 days after the VM is deleted. Data from monitoring and metering serve as the basis for the reporting of the SLA.
Log Data	Logs and metrics are collected and stored centrally according to the description of the component.
Reporting	This component itself provides the basis for reporting.
