Hostname Variable for Configuration Template

rednarb

Friends,

I need to pass the device's hostname to a command in a configuration template. I can't seem to find what the variable is to insert the hostname or system name into the CLI portion of the script! Any clues to lend? Ought to be simple but I can't find any example of it anywhere.

For example:

script SetLogPrefixJUNOS(NCM.Nodes @ContextNode, @HOSTNAME)

{

CLI

{

configure exclusive

set system syslog host 10.1.1.1 log-prefix "@HOSTNAME"

commit

exit

}

I figured it out, dumb. NCM has a different nodes table than the main orion modules use, i looked at that table and they have different names for some things, for example they call the Caption as NodeCaption, i tested that and it worked

Any of these should work from the contextnode. syntax

NodeID, CoreNodeID, EngineID, NodeCaption, NodeGroup, AgentIP, AgentIPv6, ManagedProtocol, AgentIPSort, ReverseDNS, Status, Community, CommunityReadWrite, SNMPLevel, SysName, SysDescr, SysContact, SysLocation, SystemOID, Vendor, VendorIcon, MachineType, LastBoot, OSImage, OSVersion, ConfigTypes, NodeComments, Username, Password, EnableLevel, EnablePassword, ExecProtocol, CommandProtocol, TransferProtocol, LoginStatus, UseHTTPS, UseUserDeviceCredentials, LastInventory, SNMPContext, SNMPUsername, SNMPAuthType, SNMPAuthPass, SNMPEncryptType, SNMPEncryptPass, AllowIntermediary, UseKeybInteractiveAuth, ResponseError, InstanceType, plus any custom properties you have created in your environment

Have you tried ${Caption} ? the way you are using @hostname would seem to be trying to call a hostname that would have been given at the prompts before running the script, and I'm assuming you just want NCM to just automatically use the name from whatever node you are executing against.

Thank you for the suggestion however, I have just tried that and it doesn't validate.

set system syslog host 10.1.1.1 log-prefix "${Caption}"

Validation Failed: An error occurred during script parsing. Position: Line 19, Character 61 Error message: no viable alternative at character '"' Please check script syntax.

I found an article with some relevant syntax examples, looks like @contextnode.Caption should do the job

No joy.

I tried:

set system syslog host 10.1.1.1 log-prefix @ContextNode.Caption

Got:

Error:Variable @ContextNode.Caption could not be matched. Possible causes of this are:

1) It has not been declared.

2) You are referencing an entity property which does not exist.

3) You are missing a closing bracket in a prior native block.

I'm going to tinker around with variable declaration and see if I can make this work but there is surprisingly little or cryptic (to my pea brain at least) information on this out there!

Yeah, I've done this stuff before but it is so few and far between for me I have forgotten the syntax. I've just been too lazy to log into my lab server and try to build a template using one of these to jog my memory, was hoping quick google fu would save me from work. I'll let you know if I come across the syntax when I get into the lab later this week.

Any of these should work from the contextnode. syntax

Wow, thank you so much for your help. Way above and beyond Marc!

For the record, here is the working little script:

/*.CHANGE_TEMPLATE_DESCRIPTION        Set syslog log-prefix for Juniper JUNOS devices.PLATFORM_DESCRIPTION        Juniper JUNOS.PARAMETER_LABEL @ContextNode        NCM Node.PARAMETER_DESCRIPTION @ContextNode        The node the template will operate on.  All templates require this by default. The target node is selected during the first part of the wizard so it will not be available for selection when defining values of variables. */script SetLogPrefixJUNOS(                                NCM.Nodes @ContextNode){  CLI  {     configure exclusive     set system syslog host X.X.X.X log-prefix @ContextNode.NodeCaption     commit     exit  }}
