Viraj Jasani commented on HBASE-25914:
--------------------------------------
Thanks [~stack]. The reason why Name Queue log tab is because it is a generic
in-memory queue retrieval API name. Such tag already exists in master UI too
(thanks to [~GeorryHuang]'s efforts), which contains two sub-tabs:
BalancerDecision and BalancerRejection. Both are in-memory queue implementation
maintained by master.
Generic Admin API for all queues maintained by both HMaster and RegionServer:
{code:java}
/**
* Retrieve recent online records from HMaster / RegionServers.
* Examples include slow/large RPC logs, balancer decisions by master.
*
* @param serverNames servers to retrieve records from, useful in case of
records maintained
* by RegionServer as we can select specific server. In case of
servertype=MASTER, logs will
* only come from the currently active master.
* @param logType string representing type of log records
* @param serverType enum for server type: HMaster or RegionServer
* @param limit put a limit to list of records that server should send in
response
* @param filterParams additional filter params
* @return Log entries representing online records from servers
* @throws IOException if a remote or network exception occurs
*/
List<LogEntry> getLogEntries(Set<ServerName> serverNames, String logType,
ServerType serverType, int limit, Map<String, Object> filterParams) throws
IOException;
{code}
{quote}Will the full RPC show in the UI?
{quote}
I think so and hopefully it will be scrollable. [~GeorryHuang] is my assumption
correct? As API supports limit param, let's have a drop down on UI to limit no
of recent records in UI?
