Requirements:
- Hardware platform: Cisco 1800, 2800, 3800 ISRs
- Cisco IOS Software Release: Scripts written using Release 12.4(9)T4
| Script Title | Summary | Category |
|---|---|---|
| Composite Device Health - Interface Errors View Video |
Tcl script monitors the health of physical interfaces. | Diagnostics |
| Composite Device Health - Memory View Video |
Tcl script utilizes the Memory Threshold Notifications feature introduced in Releases 12.2(18)S, 12.0(26)S and 12.3(4)T. This feature allows one to mitigate low-memory conditions on a router. | Diagnostics |
| Power and Temperature Health |
Applet monitors the environmental health of a router as defined as having at least the following components:
|
Diagnostics |
| Memory Health |
Tcl script can be used as part of an overall strategy to monitor basic device health which includes the percent utilization of:
|
Diagnostics |
| Forwarding Path Health | Tcl script monitors router interfaces that are specified by the users to track excessive process switched packets that exceed a configurable threshold based on a percent value between 1-99. | Diagnostics |
| HSRP State Change | Applet can be used on the standby HSRP router to notify a monitoring tool when an HSRP active router is no longer available or becomes inactive due to an interface state change. | Diagnostics |
| L2 WAN Failure Detection | Tcl script sends an alarm in the form of an email containing both the whole and parsed output of "show interface" when the line protocol of an interface goes from up to down. | Diagnostics |
| L3 Path Failure Detection - EIGRP Neighbor Change | Tcl script sends an email notification when an EIGRP neighbor change occurs. | Diagnostics |
| L3 Path Failure Detection - IP Route Tracking | Applet sends an email notification when an IPv4 route to a remote site is withdrawn from the global routing table. | Diagnostics |
| VPN Failure Detection View Video |
Tcl script generates an alarm when a VPN failure occurs. | Diagnostics |
| Server Failure Detection - Down State View Video |
Applet sends an email notification when the tracked state of icmp-echo to a particular server goes to a 'down' state. | Diagnostics |
| Server Failure Detection - Up State View Video |
Applet will send an email notification when the tracked state of IP SLA icmp-echo's destined for a particular server reaches 'up' state. | Diagnostics |
| Application Failure Detection | Applets provide examples to monitor application failures based on TCP port availability. Cisco IP SLA and Embedded Object Tracking are used to trigger these applets. | Diagnostics |
| Priority Queue Threshold View Video |
Tcl script periodically checks the priority queue(s) of all interfaces that have a service-policy configured. | Diagnostics |
| WAN Load Alarm | Tcl script sends an alarm via syslog & email if the WAN link specified exceeds a specified load (wan_load_threshold) for more than a specified duration of time (wan_load_duration). | Diagnostics |
| Log New Configuration After Updates | Applet will dump the most recent configuration to flash:latest-config when a change notification alarm is detected. | Network Management |
| Log Config Diffs After Updates View Video |
Applet will send only the config deltas when a configuration change notification alarm is detected using the Cisco IOS config diff feature. In addition, the output of 'show archive log config all' will be provided in an email to show the user who made the configuration change. | Network Management |
| Log User Name Information | Applet will send only the config deltas when a configuration change notification alarm is detected using the IOS config diff feature. | Network Management |
| Send Show-tech via Email | Applet will email the output of 'show tech' using the command 'sendtech'. | Network Management |
| Send Email View Video |
Tcl script serves as a template that can be used when sending an email notification is needed | User Interface |
