Configuring Historical PM Collection on BTI800 Series Network Elements
In order for PSM to retrieve historical PMs from BTI800 Series network elements, you must configure the BTI800 Series network elements to transfer the historical PM counts to the PSM server. Unlike historical PM collection for the other NE types, BTI800 Series network elements store historical PM counts in CSV files that must be transferred to the PSM server.
This procedure is required regardless of whether you are running scheduled or on-demand historical PMs.
The generated CSV files are named using the NE name. Therefore each BTI800 Series network element must be configured with a unique name to ensure the CSV files that it generates have unique names when placed on the PSM server.
Ensure the BTI800 Series network element is not also reporting statistics to the SLA Portal. You cannot use both PSM and the SLA Portal to retrieve counts from BTI800 Series network elements at the same time.
The following steps are performed using the CLI on the BTI800 Series network element:
- Configure the NTP server if one is not already configured.
The following specifies the NTP server to use, and sets the time zone to EST.
configure ntp del-server 1 configure ntp add-server <ntp_server_ip> configure ntp enable configure timezone est
- Disable any existing PM collection and file transfer.
configure pm file-transfer disable configure pm sys disable configure pm eth disable configure pm oam disable configure pm eservice disable configure pm eservice last5m disable configure interface average-rate disable
- Enable Ethernet PM collection.
configure pm eth enable
- Configure PM file transfer.
The following configures the BTI800 Series switch to transfer 15-minute and 1-day Ethernet PMs to the PSM server every hour, which is the highest recommended upload frequency. To change/decrease the frequency of the file transfer, change the setting of the
configure pm file-transfer mode sftp configure pm file-transfer target <server_ip> <username> <password> <dest_dir> <sftp_port> configure pm file-transfer upload-bin group del all configure pm file-transfer upload-bin group add 15m configure pm file-transfer upload-bin group add 24h configure pm file-transfer upload-mode frequency 0 0 60 configure pm file-transfer upload-group add eth configure pm file-transfer enable
<server_ip> is the IP address of the PSM server.
<username> and <password> are the login credentials used to log in to the PSM server.
<dest_dir> is the destination directory where the historical PM CSV files are to be placed, and consequently where PSM retrieves the historical PM CSV files. This directory is specified relative to the FTP user's home directory, and should be set to
<sftp_port> is the port number (typically 22) to use.
With these settings, the BTI800 Series network element transfers a historical PM CSV file to the PSM server once every hour. The file name includes the name of the NE (or IP address), and the GMT time and date.
If you are running on-demand historical PMs, be aware of the file transfer frequency. The on-demand historical PM data reflects the counts from the last update.
