* Real-Time Data - all data is immediately made available for search and analytics. * Real-Time Advanced Analytics - Combining the speed of search with the power of analytics changes your relationship with your data. * Massively Distributed - Elasticsearch allows you to start small and scale horizontally as you grow. * High Availability - Elasticsearch clusters are resilient — they will detect new or failed nodes, and reorganize and rebalance data automatically, to ensure that your data is safe and accessible. * Multitenancy - A cluster may contain multiple indices that can be queried independently or as a group. * Full-Text Search - Elasticsearch builds distributed capabilities on top of Apache Lucene to provide the most powerful full- text search capabilities available. * Document-Oriented - Store complex real world entities in Elasticsearch as structured JSON documents. * Schema-Free - Elasticsearch allows you to get started fast. Simply index a JSON document and it will automatically detect the data structure and types, create an index, and make your data searchable. You also have full control to customize how your data is indexed.

* Proactive - Monit can act if an error situation should occur, e.g.; if sendmail is not running, Monit can start sendmail again automatically or if apache is using too much resources (e.g. if a DoS attack is in progress) Monit can stop or restart apache and send you an alert message. * Processes - You can use Monit to monitor daemon processes or similar programs running on localhost. Monit is particularly useful for monitoring daemon processes, such as those started at system boot time from /etc/init/ For instance sendmail, sshd, apache and mysql. * Files, Dirs and Filesystems - You can also use Monit to monitor files, directories and filesystems on localhost. Monit can monitor these items for changes, such as timestamps changes, checksum changes or size changes. * Cloud and Hosts - Monitor network connections to various servers, either on localhost or on remote hosts. * Programs and scripts - Monit can be used to test programs or scripts at certain times, much like cron, but in addition, you can test the exit value of a program and perform an action or send an alert if the exit value indicates an error. * System - Finally, Monit can be used to monitor general system resources on localhost such as overall CPU usage, Memory and Load Average.
