# Scheduler
Energy Monitor offers the capacity to periodically do various tasks automatically.
Note:
- field "Name" under "Schedule" refers to the name of the task.
- In task 2, "_name" is automatically added in the list, it's the hosts's "hostname", as configured in the host configuration menu.
1. Enter "**Manage**" -> "**Scan Schedule**"
## Scheduler offers 4 types of tasks:
### 1. Autodiscover IP address
Energy Monitor can be set up to periodically scan the network for changes. If it finds a new host, it can automatically be assigned a bucket, which is a set of metrics/services that can be instantly assigned to a host. You can also specify an IP range and a domain to be searched.
Note:
- in regards to field "Top Domainname" please input only your domain name.
- Normally, the scan will return the host like: test_host.emca.pl
- By inputting domain name, ie: emca.pl, the host will be added without domain name in the "hostname" field in the host configuration menu.
- Energy Monitor doesn't need the domain name in the "hostname" field to function properly.
### 2. SNMP
- Can be used to update network interface names on networking devices, routers, switches and the like.
- Task reads from the original device, ie. a router, the label of the interface, then checks if that interface in Energy Monitor is labeled.
- If not, label will be added. If a label does exist but differs from the original one, it will be changed.
### 3. Host Update
- This task updates host's services by buckets. A bucket is essentially a group of services/metrics bundled together that can be preconfigured and added in bulk to hosts.
- You can speficy a bucket and a host range and all hosts in this range, will be assigned metrics/services from that bucket.
- Shall a bucket be modified, the next occurence of this task will update the host with the new changes, as well.
### 4. Windows Disk Label Update:
- This task is very similar in nature to #2. It populates disk labels on Windows hosts by renaming them.
- Like #2, it reads from the source, the original host. So if a disk label will change there, that disk label in Energy Monitor wil also change.
- If a label is missing all together, it will be created. If it exists, it will be changed.
