Monitoring concept

Continuous monitoring of critical components for highly available systems


Our central monitoring concept ensures that your systems are securely set-up. We are monitoring critical components and important metrics around the clock. Depending on your selected SLA, our system administrators are informed about essential incidents immediately, within the service period, and independently begin to remedy them. Our monitoring concept allows you to counteract business-critical downtimes and increase the availability and performance of your systems.


Capturing system metrics through monitoring


In addition to our monitoring, we have long-term time series of many of the operational metrics in high time resolution. This allows us to analyse past problems or read general trends. In the case of performance-relevant issues, considerably more information for analysis can be obtained.




The following components, among others, are monitored by our monitoring system:


Application


Accessibility of the login page of the application

Simultaneous connections to the application

Accessibility of LDAP server for authentication (optional)

Number of open files and processes (threads)

Various trends that indicate the application's utilization

Application memory utilization (JVM heap)

Application-specific checks: for example, insecure access permissions

SSL Certificate Expiration Date

Reverse Proxy Functionality

Database, Storage, Backup


The functionality of the database

The capacity of hard disk storage

Hourly snapshots of the file system (ZFS)

Daily backup of data to an external backup server



System


Utilization of the CPU and the main memory

Consistency between application URL and DNS records

Internet access

Correct synchronization of time services

The functionality of the mail dispatch

Installing operating system security updates




Timelines for the following metrics are recorded by our monitoring solution (extract):

  CPU load + Load

  Disk occupancy

  Network utilisation

  Memory usage (system + application)

  Java threads (http + non http)

  Number of accesses

  Application response times

  Memory consumption per process

  Application memory utilisation (JVM heap)

   Garbage collection

  Java code cache
