| Option | TOTAL_MEMORY_MB | |
| Description | Total available memory on the host in megabytes, used by the launcher to calculate JVM memory defaults | |
| Introduced Version | 1.0.0 | |
This environment variable specifies the total available memory
on the host in megabytes. The launcher uses this value when
calculating the default HUMIO_MEMORY_OPTS
settings (a heap size of 75% of total memory, plus 0.25 GB of
off-heap memory per core). If not set, the launcher determines
the available memory automatically.
