Enhanced a textual listing of instruments.

[mgcam]

Added a column for recently used staging servers so that the loaders can easily spot instruments, which write to the same server.

Suggested change

	ORDER BY date DESC];
	my $dbh = $self->util->dbh();
	# Four rather than two latest runs since NovaSeq(X) instruments have
	# two sides, which write to the same staging server.
	my $rows = $dbh->selectall_arrayref($query, {RaiseError => 1, MaxRows => 4},
	$self->id_instrument(), $run_status);
	my @globs = uniq map { $_->[0] } @{$rows};
	# We do not need more that two unique globs.
	while (scalar @globs > 2) {
	pop @globs
	}
	ORDER BY date DESC
	LIMIT 4 ];
	my $dbh = $self->util->dbh();
	# Four rather than two latest runs since NovaSeq(X) instruments have
	# two sides, which write to the same staging server.
	my $rows = $dbh->selectall_arrayref($query, {RaiseError => 1, MaxRows => 4},
	$self->id_instrument(), $run_status);
	my @globs = uniq map { $_->[0] } @{$rows};
	# We do not need more that two unique globs.
	while (scalar @globs > 2) {
	pop @globs
	}

Probably not worth it! (Thinking aloud...)

If this is to limit to 4 rows, then it is aleady done by MaxRows => 4

How about finding the last two staging areas used rather than the staging areas for last two runs?

SELECT folder_path_glob, SUBSTRING_INDEX(SUBSTRING_INDEX(folder_path_glob, "/", 3),"/",-1) staging_area, DATE(MAX(run_status.date)) mxdate FROM instrument                 JOIN run USING(id_instrument)                 JOIN run_status USING(id_run)                 JOIN run_status_dict USING(id_run_status_dict)                 WHERE folder_path_glob IS NOT NULL                 AND LENGTH(folder_path_glob) != 0                 AND id_instrument=160 AND description="run in progress" GROUP BY staging_area ORDER BY mxdate DESC LIMIT 2;

Possible. Having talked to @jmtcsngr I tried to fetch recently used staging areas rather than two last used
