• RTMT cannot download a zipped crash dump file larger than 2 GB. in context
• From Release 14SU3 onward, scheduled trace collection no longer supports an FTP server; SFTP is used. in context
• Real Time Trace View Real-Time Data refreshes every 5 seconds, and Monitor User Event polls every 5 seconds for a search string to trigger an alert or download. in context
• Trace and Log Central runs up to six concurrent trace collections, allows up to ten scheduled jobs and opens at most five files at once for viewing. in context
• Trace collection starts at Tools > Trace > Trace & Log Central > Collect Files, choosing services per node, an absolute or relative time range and active or inactive partition. in context
• Trace and Log Central uses the Selected Reference Server Time Zone and adjusts for nodes in other time zones so all nodes return the same time period. in context
• Enabling the Trace Compression enterprise parameter adds CPU cycles and can reduce overall call throughput by as much as 10 percent. in context
• From Unified Communications Manager 8.0 onward the log compression feature compresses certain log files in gzip format, the file currently being written carries a .gzo extension, and CLI view and tail commands uncompress automatically. in context
• RTMT View Real Time Data shows live trace data for up to ten services with a limit of three concurrent sessions on a single node. in context
• RTMT Remote Browse views or downloads traces directly on a node and allows a maximum of five concurrently open files. in context
• Collect Files offers a Delete Collected Log Files from the server check box that removes the collected files from the node. in context
• The default Collect Files download location is <rtmt_users_directory>\<server name>\<download time>, changeable with Browse. in context
• The RTMT Collect Files wizard accepts either an Absolute Range (start and end date and time) or a Relative Range (minutes, hours, days, weeks or months before now). in context
• In Collect Files, choosing the Zip File radio button creates a zip file of the collected traces. in context
• RTMT can schedule up to six concurrent trace collections to an SFTP server; FTP is no longer supported from release 14SU3 onward. in context
