What is a Memcached?
Memcached is a general-purpose distributed memory caching system often used to speed up dynamic database-driven websites by caching data and objects in RAM to reduce the number of times an external data source must be read.
Written in C and under a revised BSD license, Memcached's APIs provide a giant hash table distributed across multiple machines. When the table is full, older data is purged in least recently used (LRU) order.
How to monitor a Memcached?
ServicePilot makes it easy to monitor a Memcached cache requiring only the installation of a ServicePilot Agent on the target server. A resource of the database-memcached package then needs to be added via the ServicePilot web interface.
Monitored statistics collected and analyzed include:
- General measures: Bytes read, bytes written, GET hits, GET misses, threads...
- Connection measures: Current connections, total connections, connection structures...
How to install a memcached resource?
- Use your ServicePilot OnPremise installation or a SaaS account.
- Add a new memcached resource via the web interface (
/prmresources) or via API (
/prmpackagespage), the default ServicePilot agent or another agent will be provisioned automatically.
Details of the memcached package are located in the
/prmpackagespage of the software.
ServicePilot enables you to deliver IT services faster and more securely with automated discovery and advanced monitoring features.
By correlating the technology MEMCACHED with APM and infrastructure monitoring, ServicePilot is able to provide a more comprehensive view of an organization's IT environment.
This allows IT teams to quickly identify and diagnose issues that may be impacting application performance, and take corrective action before end-users are affected.
