\nElasticsearch Resourcing Requirements<\/h2>\nWe have clarified some of the wording in the Explorer Installation Guide regarding the resourcing required for Elasticsearch to function optimally.<\/p>\n \n- If Elasticsearch<\/strong> is used, allow a minimum of an additional<\/strong> 8 GB of RAM for allocation to Elasticsearch.<\/li>\n
- For large Shift Log installations, an additional<\/strong> 16 GB or greater is recommended.\n
For example: You could allocate the machine with 56 GB RAM, of which 24 GB is specifically allocated to Elasticsearch and the remaining 32 GB will be available for Explorer applications on the machine.<\/li>\n<\/ul>\n Caveat:<\/strong><\/p>\nHowever, for optimal performance:<\/p>\n \n- Do not allocate more than 30 GB RAM to Elasticsearch.<\/li>\n
- Do not allocate more than 50% of total system memory to Elasticsearch.<\/li>\n<\/ul>\n
Examples:<\/strong><\/p>\n\n- If you have a system with 60 GB RAM, you could:\n
\n- Allocate 24 GB to Elasticsearch.<\/li>\n
- Total memory available for other applications (including Explorer): 36 GB.<\/li>\n<\/ul>\n<\/li>\n
- If you have a system with 1 TB RAM available, you could:\n
\n- Allocate 30 GB to Elasticsearch.<\/li>\n
- Total memory available for other applications (including Explorer): 98 GB.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n
