With Auto Discovery, up.time can detect systems on your network =
that have an IP address within a specified range, as well as other search c=
riteria:
- the
ping
utility is used to determine whether systems are =
available on the network
- an Agent check is performed to determine which systems have the up.time=
Agent installed on them
- a WMI check is used to determine whether Windows-based systems are usin=
g WMI to gather performance metrics
- SNMP-based network devices are detected
- an SNMP probe is done to find any systems that are using Net-SNMP
Systems that are repeatedly discovered with different checks (e.g., both=
an up.time Agent and WMI implementation are detected on the same system) w=
ill by default be assigned a type based on the first check that resulted in=
its discovery. The auto-discovery order is as follows: agent check, WMI ch=
eck, network device discovery, Net-SNMP probe.
Once a list of systems in the range of IP addresses that you specified i=
s generated, you can selectively add them to up.time.
Usin=
g Auto Discovery
To use Auto Discovery for systems and network devices, do the following:=
- In the My Infrastructure panel, click Auto Dis=
covery.
The Auto Discovery window appears.
- Ensure Auto Discovery is set for Servers and Network Devices, then click Next.
- Select one or more types of network entities to include in the auto-dis=
covery process:
- Servers with up.time Agent
- Servers with Windows Management Instrumentation (WMI)
- Servers with Net-SNMP v2 or v3
- Network devices with SNMP
With each selection, additional configuration options appear.
- Optionally provide up.time Agent connection information to allow the Mo=
nitoring Station to detect systems that have the Agent installed on them. S=
elect the Use up.time Agent Global Configuration check box=
if this information has been configured (see Configuring Global Data Collection Methods for more informat=
ion); otherwise complete the following options:
- Port
The port through which the up.time Agents communicate with the up.time Mon=
itoring Station.
- Use SSL
Select this check box if the Agent securely communicates with the Monitori=
ng Station using SSL.
- Optionally provide login information for an administrative Windows acco=
unt if you would like Auto Discovery to scan for systems that are using WMI=
to collect metrics. Select the Use WMI Global Configuration check box if this information has been configured (see Configuring Global Data Collection Methods); otherwis=
e complete the following options:
- Windows Domain (optional)
The Windows domain in which WMI has been implemented.
- User Name
The name of the account with access to WMI on the Windows domain.
- Password
The password for the account with access to WMI on the windows domain.
- Optionally provide SNMP connection information to allow Auto Discovery =
to scan for servers with Net-SNMP. Select the Use Global SNMP Conne=
ction Configuration check box if this information has been configu=
red (see Global SNMP Configuration Settings fo=
r more information); otherwise select the SNMP Version tha=
t your servers are using, then complete the appropriate options:
- SNMP Port
The port on which the Net-SNMP instance is listening.
- Read Community
A string that acts like a user ID or password, giving you access to the Ne=
t-SNMP instance. Common read communities are public (enables you to retriev=
e read-only information from the device) and private (enables you to access=
all information on the device).
- Username
The name that is required to connect to the Net-SNMP instance.
- Authentication Password
The password that is required to connect to the Net-SNMP instance.
- Authentication Method (optional)
From the list, select one of the following options, which will determine h=
ow encrypted information traveling between the Net-SNMP instance and up.tim=
e will be authenticated:
MD5: A widely-used method for =
creating digital signatures used to authenticate and verify the integrity o=
f data.
SHA: A secure method of creating digital signat=
ures. SHA is considered the successor of MD5 and is widely used with networ=
k and Internet data transfer protocols.
- Privacy Password
The password that will be used to encrypt information traveling between th=
e Net-SNMP instance and up.time.
- Privacy Type (optional)
From the list, select one of the following options, that determine how inf=
ormation traveling between the Net-SNMP instance and up.time will be encryp=
ted:
DES: An older method used to encrypt information.<=
br>AES: The successor to DES, which is used with a variety=
of software that require encryption including SSL servers.
- Optionally provide SNMP connection information to allow Auto Discovery =
to scan for SNMP-based network devices. Select the Use Global Conne=
ction Configuration check box if this information has been configu=
red (see Global SNMP Configuration Settings); =
otherwise complete the configuration options as described in the previous s=
tep.
- For the Auto Discovery scan, in the Subnet field, indi=
cate which subnets or IP address ranges to scan, using one of the following=
formats:
- a single subnet (e.g.,
10.1.50
)
- multiple, comma-separated subnet entries (e.g.,
10.1.50, 10.1.51,=
10.1.52
)
- an IP address range (e.g.,
10.1.53.65-120
)
multiple subnets and an IP address range (e.g., 10.1.50, 10.1.=
51, 10.1.52, 10.1.53.65-120
)
- Select the Element Group in which these additions will=
be placed.
- Click Next to begin the auto-discovery process.
A list of the systems that match all your defined criteria is generated. T=
he time required for the list to populate is dependent on the breadth of yo=
ur search criteria.
- When the auto-discovery list has been completed, select the correspondi=
ng check boxes for all the network entities you wish to add to up.time as m=
onitored Elements.
Click Next to begin adding your selections.
As your selections are added to up.time as Elements, the progress of their=
addition is displayed.
Click Done.
All of the new Elements will appear in the selected Element group under My Infrastructure.
