Default Settings

All defaults can be overridden in the DEFAULT section of the configuration file or per-container via Tiers.

Scaling parameters

Parameter	Default	Description
`poll_interval`	`300`	Seconds between scaling cycles.
`cpu_upper_threshold`	`80`	CPU % triggering scale-up.
`cpu_lower_threshold`	`20`	CPU % triggering scale-down.
`memory_upper_threshold`	`80`	Memory % triggering scale-up.
`memory_lower_threshold`	`20`	Memory % triggering scale-down.
`min_cores`	`1`	Minimum CPU cores per container.
`max_cores`	`4`	Maximum CPU cores per container.
`min_memory`	`512`	Minimum memory (MB) per container.
`core_min_increment`	`1`	Minimum cores added per scale-up.
`core_max_increment`	`2`	Maximum cores added per scale-up.
`memory_min_increment`	`256`	Minimum MB added per memory scale-up.
`min_decrease_chunk`	`128`	Minimum MB removed per memory scale-down.

Host reservation

Parameter	Default	Description
`reserve_cpu_percent`	`10`	% of host CPU cores never allocated to containers.
`reserve_memory_mb`	`2048`	MB of host memory reserved.

Energy mode

Parameter	Default	Description
`off_peak_start`	`22`	Hour (24h) when off-peak begins.
`off_peak_end`	`6`	Hour (24h) when off-peak ends.
`energy_mode`	`false`	Reduce to minimums during off-peak. Enable via `--energy_mode` flag.
`timezone`	`UTC`	IANA timezone for off-peak scheduling (e.g., `Europe/Rome`).

Behaviour multiplier

Value	Multiplier	Effect
`conservative`	0.5x	Slower, smaller scaling steps.
`normal`	1.0x	Default behaviour.
`aggressive`	2.0x	Faster, larger scaling steps.

Backend selection

Parameter	Default	Description
`backend`	`cli`	`cli` for pct commands (local or SSH), `api` for Proxmox REST API.

SSH (remote CLI backend)

Parameter	Default	Description
`use_remote_proxmox`	`false`	Execute pct commands on a remote host via SSH.
`proxmox_host`		IP or hostname of the remote Proxmox host.
`ssh_user`		SSH username.
`ssh_password`		SSH password. Prefer `ssh_key_path` or env var `LXC_AUTOSCALE_SSH_PASSWORD`.
`ssh_key_path`		Path to SSH private key.
`ssh_port`	`22`	SSH port.
`ssh_host_key_policy`	`reject`	`reject` (verify host keys), `system` (warn on unknown), `auto` (deprecated).

Proxmox REST API backend

Parameter	Default	Description
`proxmox_api.host`		Proxmox host IP or hostname.
`proxmox_api.user`		Proxmox user (e.g., `root@pam` or `autoscale@pve`).
`proxmox_api.token_name`		API token name.
`proxmox_api.token_value`		API token secret. Use env var `${PROXMOX_API_TOKEN}`.
`proxmox_api.verify_ssl`	`true`	Verify SSL certificates when connecting to the API.

File paths

Parameter	Default
`log_file`	`/var/log/lxc_autoscale.log`
`lock_file`	`/var/lock/lxc_autoscale.lock`
`backup_dir`	`/var/lib/lxc_autoscale/backups`

Container exclusion

Parameter	Description
`ignore_lxc`	List of container IDs to exclude from all scaling operations.
