Installing IP SLA Manager
The server that you use to host IP SLA Manager must also support an installation of Orion Network Performance Monitor version 9.5 SP4 or higher. IP SLA Manager does not require any additional resources beyond those required for the underlying implementation of Orion NPM. For more information about system requirements, see Installation Requirements in the SolarWinds Orion IP SLA Manager Administrator Guide.
To install IP SLA Manager:
- Shut down any Orion NPM applications that you may have running.
- Run the installation executable.
For more information about installing IP SLA Manager, see Installing IP SLA Manager in the SolarWinds Orion IP SLA Manager Administrator Guide.
- If you are upgrading, back up your Orion database before you install IP SLA Manager, to ensure that none of your data is lost during the upgrade.
- When upgrading to Orion NPM version 10.1, you must install Orion IP SLA Manager version 3.5.1 on your primary and any additional servers before upgrading Orion.
- IP SLA Manager does not support the use of case-sensitive database servers.
Upgrading from VoIP Monitor to IP SLA Manager
Upgrading from a previous version of IP SLA Manager or from VoIP Monitor does not require you to uninstall your current installation. To upgrade IP SLA Manager, install IP SLA Manager normally. None of your historical data or customized settings will be lost in the process. For more information about installing IP SLA Manager, see Installing IP SLA Manager in the SolarWinds Orion IP SLA Manager Administrator Guide.
- Backup your Orion database before you install IP SLA Manager, to ensure that none of your data is lost during the upgrade.
- When upgrading from VoIP Monitor, you must have VoIP Monitor 2.0.2 or later installed before upgrading to the latest version of IP SLA Manager.
- If you have a large amount of VoIP and CallManager data, the upgrade may take more than 30 minutes to an hour to complete.
- You must upgrade any additional web servers or additional polling engines prior to upgrading your base installation.
IP SLA Manager and Additional Polling Engines
In order for IP SLA Manager statistics to be properly recorded by additional polling engines, IP SLA Manager must be installed on every additional polling engine you are running. To install IP SLA on an additional polling engine, run the IP SLA Manager setup program on the additional polling engine server. The IP SLA Manager setup program recognizes the type of server on which you are installing (additional or primary), and will install appropriately.
Note: For an additional polling engine to properly process IP SLA data, you must install the same version of IP SLA Manager on the additional polling engines as the version running on the primary polling engine.
Adding Devices to IP SLA Manager
To add a device to IP SLA Manager, the device must already be monitored by Orion NPM. The device must also be a Cisco device that supports SNMP v2 or v3. To confirm that the Cisco IOS release for your device supports IP SLA operations, visit the Cisco Feature Navigator, click Search by Feature, and then select IP SLAs - DHCP Operation. For more information about the management information bases (MIBs) that IP SLA Manager maintains, see MIBs Maintained by IP SLA Manager in the SolarWinds Orion IP SLA Manager Administrator Guide.
Changing the Source Node IP Address
With IP SLA Manager you have the ability to change the source node IP address certain IP SLA operations use. For example, a node has three outbound interfaces with three different IP addresses. You can effectively designate which of these IP addresses will be used as the source IP address for operations created on that node. The designated IP address will be used for the following IP SLA operation types:
- ICMP Echo
- TCP Connect
- UDP Echo
- UDP Jitter
- VoIP UDP Jitter
To change the source node IP address, edit the node in IP SLA Node Management, type then new address the IP Address field, and then click Save.
Migrating Reports to Another IP SLA Manager Installation
Custom reports that you have created for a standard installation of IP SLA Manager are easily migrated to a second IP SLA Manager installation that is typically an Additional Poller. The following procedure copies existing reports from one IP SLA Manager installation to another.
To migrate IP SLA Manager reports from one installation to another:
- Open the Orion Reports folder, located in
Program Files\SolarWinds\Orion\ on your original IP SLA Manager server.
- Select the reports you want to copy to your second IP SLA Manager server, using
Shift+Click as necessary, and then click Edit > Copy.
- Locate your second IP SLA Manager server on your network, and then open its Orion Reports folder, located in
- Click Edit > Paste to paste your reports in the Reports folder on your second IP SLA Manager server.
Your original VoIP reports are now available to your second IP SLA Manager installation.
Using Hostnames for External Targets
When using hostnames instead of IP addresses for external targets, the source node of the operation must be able to successfully resolve the hostname for the operation to be successful.
The following issues may arise in your installation of IP SLA Manager. These are known issues that are being addressed for a future release.
- The VoIP Call Path resource indicates invalid latency thresholds when highlighting values in red. This resource does not use the latency thresholds configured when editing individual IP SLA Operations as it should. Instead, the resource uses an old global threshold setting that is no longer used by IP SLA Manager.
- When customizing the IP SLA Operation Details page, clicking the Preview button results in an error.
- You cannot add the Operation Availablity resource when editing the Custom Object resource.
- Old IP SLA jobs are not deleted after configuring to the new database format and sometimes after upgrading from 3.5 to 3.5.1
- When the number of open telnet connections are limited on a router, results may take longer than expected to appear.
- Operations running on devices using a time zone code set to something other than UTC will show an incorrect time offset. The time zone will be considered to be
UTC+0. Consider the following work-arounds:
- Change the time zone code on the device to UTC format.
- Modify the
ipsla.timezones.xml file located in the
C:\Program Files\SolarWinds\Orion\VoIP Monitor folder and add a new time zone using the example provided with an offset in minutes. Restart the Orion Module Engine and Job Engine.
- CLI operations without read/write SNMP credentials cannot be deleted. To work around this issue, specify the read/write community string for the operations you want to delete before deleting them.
- Hops are not displayed for ICMP Path Echo operations when the operations have been manually created with an invalid configuration. In this situation, the operation status is still displayed as Up, but will only report the entire round trip time instead of each individual hop.
> characters in graph names causes rendering failures. To work around this issue, do not use the
> character in your graph names.
- IP SLA Manager only reports what the network devices are reporting. In some cases, path operations will not show all hops in a path or show one hop more than once because the device is reporting these hops inaccurately.
- URLs that have uppercase letters for "ftp" and "http" are not processed properly. When creating or editing IP SLA operations, type URLs using lowercase letters for
http. For example,
http://solarwinds.com instead of
- Reports that include details from two identical operations will only list one instance the operation.
- If the SolarWinds Information service is stopped, IP SLA web resources may display SQL errors.
- IP SLA Manager will continue to poll and display IP SLA operation data after unmanaging associated nodes.
- Additional pollers may indicate a "down" status when the poller is actually up and running on the Collector Services resource.
- The Operation Availability resource does not have an Edit button to allow users to configure the resource and specify a date range.
- There is not a way to change the operation number of an existing manual operation created by the user.
- When editing IP SLA Node properties, clicking Use Default does not set the source IP address to the IP address assigned to the Orion node.
- Cisco Call Manager version 4.1 is not fully supported at this time.
- Administrative functions may be limited if your IP SLA Manager server and your Orion NPM server are not in the same domain. SolarWinds recommends that you install IP SLA Manager on the same server as Orion NPM.
- An SQL exception may occur when you try to open IP SLA Manager on an additional Orion Web Console if the Orion server hosting the shared database does not also have IP SLA Manager installed. SolarWinds recommends that you not install IP SLA Manager on an additional Orion Web Console unless the original Orion server is also hosting IP SLA Manager.
- German-specific characters may not display correctly.
